Phineas and Ferb originally ended with its fourth season in 2015, with Povenmire and Marsh continuing to do other work until Povenmire signed a deal with Disney Branded Television at the start of 2023 for a fifth and sixth season. Development began in May, with voice recording commencing by September. The writers' room featured both new and returning writers, and notably saw Vanessa Doofenshmirtz's actress Olivia Olson join her father Martin as a writer. The season has received praise for its return to form, entertainment value, cast performances and characters, although some criticised its lack of reinvention.
Premise
"The new season of Phineas and Ferb will follow the inventive stepbrothers as they tackle another 104 days of summer. Candace is more determined than ever to finally bust her little brothers while their pet platypus, Perry, continues to lead a double life as the suave Agent P, whose sole mission is to thwart Dr. Doofenshmirtz from taking over the Tri-State area."
As summer vacation begins, Phineas, Ferb, and their friends create five elaborate attractions for the annual Start of Summer Block Party, while Candace tries to bust them. Meanwhile, Perry learns that Doofenshmirtz has resumed his evil ways and intends to use a "Vaporize-inator" to destroy anything he finds annoying. During a skirmish, the inator accidentally hits Linda, vaporizing her.
After Linda is accidentally turned into a living cloud by Doofenshmirtz's Vaporize-inator, Phineas, Ferb, Candace, and their friends race to save her before she dissipates. Meanwhile, Doofenshmirtz turns the cloud into a storm that endangers the neighborhood block party.
Phineas and Ferb build a giant submarine sandwich submarine from real food and travel with their friends to the bottom of the Mariana Trench. Candace tags along, neglecting her obligation to compete in a sandcastle contest. Meanwhile, Dr. Doofenshmirtz creates a food-stealing -inator while stuck at home waiting for his oven repairman.
Phineas and Ferb develop gecko-inspired climbing gear to explore Danville as Candace takes her driving test and tries to bust them. Meanwhile, Doofenshmirtz uses his "Red/Green Shift-inator" to manipulate traffic lights and rush home before his groceries spoil.
Phineas and Ferb build a giant circular ice pathway on a hot summer day, riding it on luges across Danville with their friends. Meanwhile, Doofenshmirtz uses a "Dry-Off-inator" to replace a water park's water with oil made from Doonkleberries.
Candace and Doofenshmirtz unknowingly share a therapist, Dr. Mosley Shamai, who suspects a link between their experiences through Perry. After investigating and compiling evidence, Shamai attempts a public exposé, but Perry destroys the proof using Doofenshmirtz's "Self-Destruct-inator".
Phineas and friends create a giant zoetrope called "Tropey McTropeface", which rolls away after Doofenshmirtz's plan to tip City Hall misfires. The zoetrope inadvertently captures the "Mother Mugger", while Perry stops Doofenshmirtz in time for his bath with Candace.
Phineas and Ferb build a massive, intricate bookcase for Lawrence after his collapses, but must defend it from an army of anthropomorphic plants created by Doofenshmirtz's "Face-Plant-inator." Meanwhile, Candace attempts to bust the boys by using psychological tactics on Linda.
Linda and the boys take Perry to the veterinarian for his checkup, and Perry must avoid being microchipped at all costs. Candace tags along to see Jeremy working at Mister Slushy Dawg. As the appointment line is long, Phineas and Ferb build a pet grooming contraption during the wait. While at Slushy Dawg, Doofenshmirtz spots Perry at the vet and goes to antagonize him. After being mistaken for a temp vet doctor, Doofenshmirtz sees an opportunity to chip Perry as a "freebie" evil plot. As Perry and Doofensmhirtz evade one another through the clinic, Doofenshmirtz is sent through the kids' contraption getting stuck in it, pressurizing it to launch away. The boys decline to have Perry chipped after his appointment.
Guest stars: Kelly Dempsey as Receptionist, Mindy Sterling as Veterinarian
The kids have a game of rocket-powered lacrosse while sending a ball between Danville and Africa with a giant racquet. Perry is called in late to deal with Doofenshmirtz's latest plot. Carl goes to his series of part-time jobs, where incidentally Doofenshmirtz is pulling off his plot to bother people using live fish; Monogram tells Carl to help Perry sort this out quickly because of his expensive overtime pay. Carl assuages the issues that Doofenshmirtz creates as Perry pursues him across a restaurant, a birthday party, and during a pizza delivery. Perry foils Doofensmhirtz's plot to put a fish in the hands of everyone in Danville; an overload of fish causes the giant racquet to fly away. Carl delivers the pizza to Monogram, who makes his parking at O.W.C.A. free in return for his efforts to help the organization.

"The Aurora Perry-Alis"

The Flynn-Fletchers takes a cruise to see the Tri-state Aurora, but cloud cover threatens to ruin the spectacle; Phineas and Ferb use clown balloons full of helium to lift the ship above them. Meanwhile, Doofensmhirtz brings Vanessa there as his supposed "break from evil"; Doofenshmirtz uses a "travel-size-inator" to shrink and steal various items around the ship, and Perry is sent to stop him; Major Monogram's aunt Olga and his son Monty are also aboard. As Vanessa and Monty begin to reconcile their relationship, Doofensmhirtz and Perry are shrunk and they fight. The inator misfires, shrinking both the balloons to bring the ship down, and the clouds so the Aurora is visible. This thwarts Candace's attempt to bust the boys, and as Doofenshmirtz reverses the shrink effect on himself and Perry, he is arrested for "bringing a pet on board".
Isabella leads a Fireside Girls meeting to determine what cupcake flavor to bring for the Annual Fireside Cupcake Jamboree since Ms. Feyersied cannot make it. Perry has to ensure that Doofenshmirtz renews his license to conduct evil business in the proper fashion, and O.W.C.A.’s business license too. The Fireside girls reach an impasse over whether to bring vanilla or red velvet cupcakes, and they descend into chaotic disarray. Doofenshmirtz struggles through an evil assessment, Perry renews O.W.C.A.’s license, and Doofenshmirtz returns home, turning off his accidentally turned on "uncooperate-inator". This stops the girls' violence and they agree with Isabella's compromise.
As Phineas and Ferb take Isabella for a ride on a space-faring giant pogo stick, Candace gets suits of herself made from Buford's collection of life-sized molds, aiming to disguise Linda to confuse the "force" that ruins her busting plans. Doofenshmirtz's "Leftover-Revive-inator" has made his potato salad sentient and hostile, so Perry works to help him stop this. Candace "tests" her hypothesis with Buford. As Stacy and the other kids don Candace suits, Candace cannot find Linda amongst the disguised Candaces. Doofenshmirtz's inator misfires onto a stray Candace suit, and the potato salad monster launches the boys' pogo stick into orbit, ruining her busting plan. The sentient suit has a cliffhanger ending.
As Stacy learned of Perry's dual identity secret last summer, Perry shows her an instructional video on how to deal with the knowledge. Candace and Stacy serve food to a symposium of doctors and scientists, which Doofenshmirtz attends and takes a "tag and bag" challenge with Doctor Diminutive. When Perry is captured by the doctors, Stacy gives chase, and with Monogram's cognizance, she uses her particular set of skills to break into L.O.V.E.M.U.F.F.I.N. headquarters and rescues Perry from being executed by hippopotamuses, receiving a fedora from him as a token of his gratitude.
Phineas and Ferb leave Isabella, Baljeet, and Buford to build something cool while they are with Linda; Candace decides to try and bust them. Meanwhile, Doofenshmirtz turns himself into a hideous moth, damaging Perry's hat such that he seeks a haberdasher to fix the microchip inside to avert an O.W.C.A. security breach. The three kids decide to combine their efforts to produce something impressive enough for Phineas and Ferb. Doofenshmirtz breaks into the haberdasher's office, and Perry defeats him by using a teleporting hat to obtain a laser gun from Doofensmhirtz that turns him back to normal. A misfire from the haberdasher turns the kids' invention into a moth that flies away before either Isabella can show Phineas and Candace can show Linda.
Baljeet is invited to audition for the next Space Adventure film but does not know how to act so the other kids build him an immersive set. Meanwhile, Doofenshmirtz plans to zap his brother Roger with a "Deface-inator" to make his face instantly forgettable. Baljeet struggles getting into character, but the other kids stage an attack from an animatronic slug monster so they could elicit a true performance from Baljeet. The film's director Katherine Marshall reveals that Baljeet was asked to be an extra in the film instead of the lead character Exterra, but sees his performance and decides he is too good to be an extra. Doofenshmirtz's inator hits Roger's new statue, which boosts Roger's reputation when they believe Roger is showing humility. Katherine takes the set, foiling Candace's attempt to bust the boys.
Meap believes that Big Mitch has been running fake tours as a front to obtain funds in search of the "Lost Treasure of Zachariah Yore" to fund his criminal empire. When his Alliance does not believe him, he goes rogue and reunites with the Flynn-Fletcher kids and their friends for assistance. The kids create "Stabby Barf Pain", a combination of all four seasons, to lure Mitch to Earth. Candace and Meap investigate the location of the treasure, tracking it to the Gateway Arch in St. Louis, Missouri. The alien tourists start to trash the city, but the kids are able to wrangle them together through a performance. Candace and Meap get caught infiltrating Mitch's ship and "accidentally" reveal the location of the treasure. As Doofenshmirtz has Perry help him find new ways to act "maniacal", Mitch steals Balloony, so the two follow onto the ship. As Mitch pulls the Arch out of the ground, the Alliance arrives and learns Meap was telling the truth, forcing Mitch to flee; Doofenshmirtz prevents the ship from self-destructing. Mitch steals Meap's ship, but he and Candace trick Mitch into pressing the self-destruction button, and he is captured. The Alliance Commander and Meap reward Candace for her bravery, and they take the boys' Stabby Barf Pain machine.
Phineas, Ferb, and their friends have a slumber party at the same time Candace is having one with Stacy and Vanessa. Meanwhile, in a bid to one-up his neighbor who spoils all TV shows, Doofenshmirtz plans to watch the finale of the series Acquaintances and spoil it to the entire Tri-State Area with a giant megaphone. The kids hang out in an inflatable dome where the floor is made of popcorn to watch movies, while Stacy and Vanessa attempt to dissuade Candace from busting the boys. Doofenshmirtz's "Awake-inator" fails to keep him awake, and Perry destroys both of his machines. Stacy and Vanessa join the kids in their dome, so Candace forcefully drags her sleeping mother outside to see it. The inator misfires on some birds, who eat the popcorn and pop the dome, causing it to fly away.
Phineas and Ferb build a "forced perspective" old west styled town in the backyard to convince Baljeet to like western movies. While Doofenshmirtz is out of town, Major Monogram and Carl get lost while on an excursion in the swamp, so Perry goes after them. Perry gets caught in a trap and taken to the shack of Doofenshmirtz's cousin, Bubba, who intends to eat Perry. Monogram and Carl discover Perry and the three manage to escape Bubba, who crashes into a beaver dam. Baljeet gains a fondness for western movies, and when Linda arrives, the town is revealed to be just a tiny model, which Candace confusingly points out is not how "forced perspective" works.

The Candace Suit brought to life by Doofenshmirtz's leftover-revive-inator attempts to eat Jeremy, who runs for shelter at the Flynn-Fletchers' house. The Candace Suit eats Doofenshmirtz and tries to pass herself off as the real Candace before she slips on a banana peel and spits him out. The kids give chase to the Candace Suit, which fights the real Candace, swallows her, and successfully passes herself off as real for a day until Jeremy becomes suspicious and has Phineas and Ferb use their banana peeler to free the real Candace. Buford translates the Candace Suit's garbled speech that she had been feeling lonely ever since being brought to life. To make sure the Candace Suit is with somebody while also keeping humanity safe, the kids bring her to the Himalayas to live with Klimpaloon.
Linda suspects that Samantha Sweetwater - a friend from her book club and mother of Fireside Girl Adyson - does not actually read the books. Linda and Candace discover that the club's latest book has been made into a movie and decide to bust Samantha. They infiltrate the Sweetwaters' backyard while Samantha is driving Adyson, recruiting their neighbor Irving. They see that the book has barely been touched but are unable to get closer when the Sweetwaters return early, so they go to the movie theater to catch Samantha. However, they discover that the entire book club could not finish the book and is at the theater to watch together. Samantha admits to Irving that she never reads the books. In the background, Linda constantly sees a giant tube man without realizing her sons built it, and Perry stops Doofenshmirtz from covering the entire Tri-State Area in guacamole.
Doofenshmirtz takes Vanessa to Drusselstein to take her citizenship test, which he also decides to take since he was never able to finish his as a teenager. When they arrive, Doofenshmirtz is surprised to see how modernized the town has become, and how significantly easier and less humiliating the citizenship test is, disappointing him as he believes seeing the depressive state of the town he grew up in would give Vanessa her own "tragic backstory". He retools his original Inator into one that begins reverting the town back to its more primitive self, until Perry stops him. He ultimately decides to do what his parents never did for him and be there for Vanessa, and the two receive their citizenships. Meanwhile, Linda loses her wedding ring in the sink pipes, which fall deep below the house, so Phineas and the gang build a massive drill to head underground looking for it. Candace falls into the hole (briefly passing through Perry's lair unknowingly), is chased by mole people wanting her to be their Queen, and reunites with the kids. They find the ring and are blasted out of the underground by a flood of water thanks to Doof's inator.
Phineas and the gang create a giant birdhouse on top of their tree in order to attract the Mockmacaw, a bird with the capability to shapeshift into anything and anyone, hoping to get a picture of it. Meanwhile, Perry discovers Doofenshmirtz's lab has been taken over by giant mantises; thanks to a book on Mantis Facts given to him by Vanessa, Doofenshmirtz was inspired to use an Inator to make them bigger to deal with other bugs, only to make them too big. Doofenshmirtz is suddenly proposed to by one of the mantises, which he accepts and orders them to capture Perry. Perry soon informs Doofenshmirtz that mantis women eat their husbands, which they plan to do to him, forcing them to flee again. At the same time, Phineas and the gang manage to attract the Mockmacaws, but are unable to get a picture of their bird forms. In the city, Perry gives Doofenshmirtz a battery to power his Inator, allowing him to shrink the mantises back to bug size. However, one of the rogue blasts hits him, shrinking him to their size. Candace eventually notices the birdhouse and tries to get Linda to see it, only for it to shrink thanks to another rogue blast. Doofenshmirtz tries to grow himself back with the Inator, but accidentally shrinks himself even smaller than the mantises, and is surrounded by them. Later, Candace starts to freak out seeing Linda and the kids as Mockmacaws, and even herself starting to become one.

On a peculiarly cloudy day, Candace fails to bust the boys' giant robotic scarecrows. Meanwhile, Doofenshmirtz has created an inator that projects people's dreams so he doesn't have to hear them poorly described. He hits Perry with it, revealing his dream where he becomes a giant and accidentally destroys the city. He then fires it at Vanessa, showing her fighting off an army of zombie Ducky Momo's. Perry begins battling Doofenshmirtz, causing the inator to misfire throughout the city. Buford and Baljeet are hit, revealing a dream in which Baljeet has become a brain monster intending to infect Buford and the others. Candace is hit and dreams of being a medieval warrior, trying to bust the boys while evading the "mysterious force". Ferb has a surrealist arthouse dream. Isabella dreams of a cupcake takeover that she and the Fireside Girls battle. Linda dreams of being stalked by Candace in the shower. Doofenshmirtz is finally hit and dreams of taking over the Tri-State Area. Suddenly all the creatons from the past dreams break out of the projector, which Perry fights, only for it to all still be part of Doofenshmirtz's dream; Perry destroys the inator.
Phineas, Ferb, Isabella, and Buford ride floating dandelions while Baljeet observes from below. Irving appears, wanting help to create an invention to impress Phineas and Ferb, so Baljeet agrees to help him. Candace decides to go for a different approach and act "casual" to trick the "mysterious force" in her effort to bust the boys. Meanwhile, Doofenshmirtz has created and is wearing a device that makes him "the centre of his own universe", causing makeshift planets to orbit around him at an increasingly dangerous rate. After some trouble, Perry is able to press the self-destruct button on the suit, destroying the planets and saving Doofenshmirtz. Just as Phineas and the kids finish playing on the dandelions, Irving and Baljeet arrive with their flying unicycle, only for it to be blasted away by one of the planets before they can show the others. Irving is ecstatic one of his inventions has disappeared just like Phineas and Ferb's, and runs off to make more.

A Doofenshmirtz livestream is interrupted by the presence of rival Major Monogram, who disputes the fact that O.W.C.A. only exists to thwart Doofenshmirtz's evil schemes. Viewers suggest L.O.V.E.M.U.F.F.I.N. square off in soccer against O.W.C.A., with the stipulations that if the former wins, Monogram shaves his mustache and Carl's head, and if the latter wins, Doofenshmirtz has to shave his head. Back at the Flynn-Fletchers, Buford has trouble when playing a game of "Can You Hit That Thing with a Stick", a game that even Candace finds dull, so the others try to help his aim by creating a practice arena. Doofenshmirtz's Bring-Me-A-Ringer-inator summons professional player Cristo Fernández to act as L.O.V.E.M.U.F.F.I.N.'s ringer, with Vanessa becoming the team's cheerleader. Noticing Fernández's presence during training just before the match, Monogram recruits professional player Megan Rapinoe as O.W.C.A.'s ringer (also her house was being fumigated). With Klimpaloon officiating and Dink Winkerson, who escaped from prison, narrating, the match begins and immediately devolves into insanity. The match tied, Fernández and Rapinoe leave, and Monogram joins the field himself but is shown a red card due to aggressively tackling several L.O.V.E.M.U.F.F.I.N. scientists and Doofenshmirtz himself. Due to divine intervention from Phineas and Ferb's use of jets to shift the Earth eight inches to the left, Doofenshmirtz's penalty kick misses, leaving both teams tied. Monogram and Doofenshmirtz concede defeat, with the former acknowledging the game helped him understand the importance of Doofenshmirtz and L.O.V.E.M.U.F.F.I.N to O.W.C.A.'s operation. Both Monogram and Doofenshmirtz, upholding their ends of the deal, shave their heads, but Carl escapes before he can shave his head.
It is Danville Day, and Phineas and Ferb plan to spruce up the festivities by building a city-wide carnival ride. With their parents attending Roger's speech, Candace is naturally left in charge. At Doofenshmirtz's, he realizes Vanessa's college essay has named his brother-turned-city-Mayor Roger as her "most positive role model", which upsets Doofenshmirtz to the point of creating the Dooflicate-inator, which gives its target his personality and his Drusselsteinian accent. The beam instead hits Phineas, Ferb, and the other kids, turning them evil in front of Candace's eyes. The kids repurpose the rides into Fun-inators to take over the Tri-State Area. While Perry fights Doofenshmirtz in an attempt to wrestle control of the Dooflicate-inator away from him, Vanessa tells Candace every inator has a self-destruct button, which when pressed will revert everyone back to normal. Candace is able to find the self-destruct button, but is trapped in a giant hamster ball that is soon launched into the Fun-inator's self-destruct button, which turns everything evil into an explosion of glitter and confetti. Reuniting with her father, Vanessa tells him she only mentioned Roger to boost her college chances, revealing that it was not out of genuine respect for him, which makes Doofenshmirtz proud. Perry then destroys the Dooflicate-inator, turning everyone back to normal.

Against a sick Buford's wishes, Baljeet shows him an episode of his favorite show, Space Adventure, titled "Gauntlet of Death". The crew of the U.S.S. Minotaur - captain Dirk Mortensen, lieutenant Zarna, cadet Sophia Sharkboard, pilot Nosh, security guard Lomond, and robot DSL-4 - steal the secret plans for the Spiky Ring, a new superweapon being constructed by the Honey Badger Empire and find out their next target is Earth. Dirk alerts the Honey Badger fleet and provokes their commander, Rrrrg, prompting a chase through the cosmos that ends on them crash-landing on the Moon, and the pursuers all combining into a large spike that crashes into the Pacific Ocean, ending the episode on a cliffhanger. As Baljeet prepares to show Buford the next episode, text reveals that Buford never actually liked Space Adventure, feigning interest only so he can infect Baljeet with his cold.
The annual Tri-State Area Droogenfest, which revolves around the signature dish of droogen strudel, is being held, and Fireside Girls Troop 46321 is tasked with creating a authentic droogen strudel to appease Drusselsteinian emissaries, who are planning to strike a trade deal with the Tri-State Area should the dish be perfect. Phineas and Ferb have created the largest doonkelberry for showcase at the festival; Perry is told to investigate Doofenshmirtz's presence. Doofenshmirtz's failed attempt to join Isabella and the Fireside Girls ends up reuniting him with her after their shared space adventure. Perry arrives, and Doofenshmirtz reveals he has a hatred of droogens and wants to swap them out with the Droogen-Chocolate-Swap-inator. While the inator is destroyed, it successfully swaps all the droogens with chocolate, causing the emissaries to cancel their trade deal and threaten to downgrade the Tri-State Area to a Bi-State Area. Doofenshmirtz works together with Isabella and the Fireside Girls to bake another strudel, while Perry distracts the emissaries before they are able to leave so they can taste the new strudel. Satisfied with the strudel, the emissaries go through with the trade deal; Isabella gives her troop and Doofenshmirtz patches (the latter after he revealed he was the creator of the inator). Doofenshmirtz reveals that Isabella looks very similar to his dentist, a male dentist who has a striking resemblance to Isabella.

Doofenshmirtz has created a powerful inator, the End-All-Be-All-inator, which turns out to be so powerful, the entire building goes out. Seeing a man powering a treadmill solely by running gives him an idea: using kinetic energy generated by humans to power his inator. An infomercial Doofenshmirtz has made promises free workouts, and inadvertantly discloses his true intentions; Perry goes to the new gym, titled the Doofnasium, to investigate. Meanwhile, Phineas and Ferb have created a land boat that works by temporarily altering the molecules of asphalt on the road, changing them to liquid, to allow movement; they pass Candace, who is on a date with Jeremy. Seeing the boys, Candace takes her boat (and Jeremy) on land, intending to catch - and bust - her brothers. Good timing, too; her mom is having her hair done, and the boys will cross by the building she is in soon. Doofenshmirtz's inator is overloaded by Perry as he fights his nemesis, which ends up causing a power surge across town. Linda's hair becomes frizzled, which means she does not see the boat; it ends up sinking underground, just as the farmer and his wife argue about transportation around an underwater lake.
Phineas and Ferb showcase Croquet Y-8, a giant-sized intermediary between Football X-7 and Hockey Z-9 that uses quantum portals to hit goals placed around the world. Meanwhile, Candace, wanting to take up multitasking, is working with Jeremy on a video about Perry for college credit. This leaves Perry at an impasse: he is needed to do the video, but he has to come to his briefing with Monogram. Perry deploys a robotic Perry decoy, and goes down to his lair, where he is told he has to defeat Doofenshmirtz, who has been taking up animal husbandry, in less than three hours. Doofenshmirtz, who has been wrangling sheep, has created the Go-to-Sheep-inator to help everyone in Danville go to sleep in order to take over the Tri-State Area. With time on the line, Perry immediately attacks Doofenshmirtz, and is able to use a ball of sheep he created against him, defeating him with 30 seconds to spare. Meanwhile, under Jeremy's supervision, the Perry-bot begins to malfunction and go haywire, while Candace is outside watching the Croquet Y-8 game. Candace gives up on multitasking as the ball of sheep Perry created takes away the croquet stuff, leaving the backyard with the usual sights of nothingness, but the tree. The Perry-bot finally explodes as the real Perry returns, with Jeremy having obtained good footage overall. The giant sheep ball ends up at the farmer and his wife's sheep farm.

Buford asks Phineas and Ferb for help with a big ball of Christmas lights that ended up being so heavy, it collapsed the Van Stomms' garage. The two use a pair of drones they used earlier for chores to put on a light show. Meanwhile, Vanessa and boyfriend Monty arrange a dinner date with their fathers and their sidekicks, Norm and Carl, respectively. Doofenshmirtz, who has completely ignored Vanessa's pleas for good behavior, has secretly installed the Tableturn-inator, a device that spins a table, allowing him to get the best food. Monogram soon finds out Doofenshmirtz and Norm are both present; soon, childish arguments begin for control over the red chair, where Doofenshmirtz has installed the switch, devolving further into food fights. Soon, Perry, who was invited by Monogram, arrives and admonishes his rival and superior for their behavior. However, this leads to yet another argument as the inator shorts out, making it spin and lift into the air. Phineas and Ferb's drone show is well-received by the gang; shortly after the kids leave, Candace, seeing an open goal, attempts to use the drones to bust the boys, but the flying restaurant crashes right into the drones as she brings her mom out for yet another failed bust. Perry is able to disable the inator, restoring stability to the restaurant; Doofenshmirtz and Monogram reconcile, and reaffirm their rivalry - agreeing not to interfere in their kids' relationship. Speaking of their kids, they admit they genuinely like each other amidst the chaos; and the bill Doofenshmirtz is given includes damages to the restaurant, which he attempts to trick Monogram into paying for it.
Phineas and Ferb unveil the Bread Bowl Hot Tub, an invention long-desired by Buford ever since the summer began. Finally getting his big break, Buford spends time in the hot tub, only to find himself stuck in a remote island; such is the result of Doofenshmirtz's new inator, the Carb-Away-inator, which pushes away food with a high amount of carbohydrates (i.e. bread). When Perry attempts to thwart him as usual, he tells his rival he has made the inator so he can improve his health. Now stranded and with no way to find food, Buford's isolation makes him hallucinate the voice of the hot tub, which he named "Chowdina"; the hot tub tells him to commune with nature, but his pacifism does not last long as he immediately finds Chowdina being attacked by rogue seagulls. Witnessing this happen, Buford builds a raft and, with Chowdina, braves the rough conditions; he soon finds himself floating back to Danville due to the Carb-Away-inator's effects being reversed, bringing all bread, including Chowdina, back to Danville (Buford believes it is the "power of friendship" bringing them home). Doofenshmirtz's attempt to improve his health is thwarted by his cravings for bread, so he asks Perry to destroy the inator. Doing so makes all the bread fall to Earth, where Chowdina crashes into the ocean and disintegrates, much to Buford's sadness; he soon accepts her fate, telling the others that Chowdina will forever live on in his heart.

With Doofenshmirtz away, Major Monogram has decided to conduct a routine test of Perry's lair entrances with Carl as his lab rat. Meanwhile, the gang decides to conduct a (non-bustable) activity of trying to find the perfect mix for an Arnold Palmer. Phineas has Isabella score the drinks, Baljeet on chemistry balance, and Buford on quenchability. While Carl tests the entrances, he ends up getting stuck on one of the entrance tunnels. Candace gets wind of a giant juice maker the kids have made, but ruminates on whether to bust them or not, as the "Mysterious Force" would end up taking it all away by the end of the day anyway. Suddenly, she hears the Mysterious Force (a.k.a. Monogram talking to Carl), who tells her to wiggle. After she asks the Mysterious Force to give her a sign, it immediatly complies and indeed, shows her one, so she calls Stacy over to show her the situation. While the kids continue to test Arnold Palmers, Candace shows Stacy around the house to prove that the Mysterious Force is real, and is able to convince her; Candace calls her mom to get home within ten minutes. Meanwhile, Monogram has been attempting to help Carl get out of the tunnel as he receives an alert that Perry's host family are on their way home, while Doofenshmirtz's patience with a pool boy finally runs out as he makes an impromptu inator - the Bring-Me-a-Drink-inator. The kids' testing devolves into arguments, solved by a mint leaf that makes the Arnold Palmer perfect. After Carl points out one of the entrances that may be able to free him, Monogram engages many entrances, while Candace brings her mom ...to the kids' Arnold Palmer stand. Candace brings them to the back, but the juice maker has disappeared, as Monogram this time makes the invention disappear... landing right on top of Doofenshmirtz, who is quenched. Perry disables the last entrance just in time as yet another Candace busting attempt fails spectacularly; Carl has finally completed the routine text, but has only scratched the surface as he now needs to test all the international entrances, too.
A shocked Buford and Baljeet informs Phineas and Ferb that their favorite TV series, Stumbleberry Finklebat, has been cancelled due to unresolved contract negotiations. They decide to build a dungeon-crawling experience inside a dodecahedron die, one that Candace reluctantly joins as she dislikes LARP. Meanwhile, Doofenshmirtz is on the lookout for love on a dating app; against his daughter's advice, he joins the cast of a reality dating show titled Passion Villa, where he is joined by the other contestants: Thad, Theo, and Evan. Vanessa cringes at her father's debut in Passion Villa, while Norm is fascinated. The gang, joined by many others, enter the dodecahedron and explore the dungeon to write their own conclusion, but Buford falls into a trapdoor, so the gang go forth to rescue him. Encountering a booby-trap filled section of the dungeon, Candace nonchalantly walks past all the traps and saves Buford, while Doofenshmirtz decides to shake things up with his new inator, the Shake-It-Up-inator, which eliminates the other contestants. Monogram, shocked by this turn of events, has Perry join the fray, where he immediately attacks Doofenshmirtz. Back at the dungeon, the gang finds the last shard of Darkling Dungeon, but encountners the Enigmata Obscura: the Puzzle Knight and his minions. Again does Candace find the solution: magnetizing the wall. She is eventually cornered, but the Man in Really Dark Grey (Jeremy) saves Candace and defeats the Enigmata Obscura. Their conclusion to Stumbleberry Finklebat written, the gang exits the dodecahedron as Doofenshmirtz not only eliminates himself, but also makes the dodecahedron shake away. At a restaurant, Norm meets "Robotina", only to end up "humanfished".
Phineas and Ferb was renewed for a fourth season in August 2011.[15] Originally set to be the final season, it concluded with an hour-long finale, "Last Day of Summer", on June 12, 2015. Povenmire and Marsh remained with the network and together created the series Milo Murphy's Law (2016–2019),[16] after which Povenmire solely created the series Hamster & Gretel (2022–present).[17] In April 2019, Disney announced a one-off film, Phineas and Ferb the Movie: Candace Against the Universe, and that it would be released on its then-new streaming service Disney+;[18] the film premiered on August 28, 2020.[19] On January 13, 2023, it was announced that a deal between Povenmire and Disney Branded Television would renew Hamster & Gretel for a second season, and revive Phineas and Ferb for two new seasons with 20 episodes each.[13] In March 2023, it was revealed that Marsh would also return as executive producer and voice director for the revival.[14]
Development on the fifth season of Phineas and Ferb began in May 2023, at which point Povenmire confirmed the then-ongoing Writers Guild of America strike would not affect its production.[20] Povenmire and Marsh admitted their concerns that they would have trouble coming up with new ideas for the revival, but explained those concerns were alleviated due to their confidence in the writers' room, which contained both returning and new writers. They cited seven episodes in particular as standouts which they felt would appeal most to the returning audience.[21] Marsh said that the returning animators had the benefit of the time to conceive many ideas they had wished were done in the original run, while the new animators brought "energy" to the writers' room with their appreciation of the show's run during their childhoods.[22] Vanessa Doofenshmirtz voice actress Olivia Olson joined the writers' room this season, after shadowing under her father Martin Olson—who wrote for the original run—as a writing team with him.[5]
Among the biggest changes to the series was that episodes were script-driven rather than storyboard-driven, reflected in the narratives of episodes like "Deconstructing Doof" and "Lord of the Firesides".[22] Povenmire stipulated that the storyboard artists were still given creative freedom, just that they were given more information and flexibility with the creative process.[22] Povenmire pointed out the challenge of writing "Meap Me in St. Louis", based around the incorporated scenes in a fake movie trailer shown in a previous episode, with most shots being entirely recontextualized beyond expectation.[22]
Animation
This season sees the debut of new art director Nadia Vurbenova, and workflow with animation is managed via the Storyboard Pro digital program used on Cintiq tablets.[22] Having previously worked on Candace Against the Universe and Hamster & Gretel, Filipino animation studio Snipple Animation works on the season.[23] Main poses are done by local animators while Snipple handles the inbetweening.[22]
Recording
Voice recording began by September 2023, and was not affected by the then-ongoing 2023 SAG-AFTRA strike.[24] Candace Flynn actress Ashley Tisdale was concurrently pregnant during voice recording and refused to record new screams, feeling it would "scare the baby"; she suggested the producers use any of her "17 years" worth of archive audio instead.[25]
The opening credits theme has undergone slight changes for the new season; the first line was changed to "There's another 104 days of summer vacation" (for episodes 2 to 6 only), and Phineas Flynn actor Vincent Martella re-recorded his lines for consistency with how Phineas sounds temporally.[3]
Release
Broadcast and streaming
The fifth season premiered in summer 2025, with the first two episodes airing on June 5 on Disney Channel, and the first ten episodes streaming on Disney+ starting June 6 in the United States and select international markets.[8] A sneak peek of the new season premiered on May 26, 2025.[12][1] A sneak peek of the first episode was released on May 21.[8] The season is set to conclude sometime in January 2026, and the final ten episodes will be available to stream on Disney+ the same month.[26]
Promotion
In April 2023, a press release commemorating the 40th anniversary of Disney Channel confirmed that the revival will air on the network.[27] The revival was originally scheduled to be released in 2024.[28] At Disney Television Animation's presentation during the Annecy International Animation Film Festival in June 2024, Povenmire and Marsh made an appearance to promote the series and give details on the production.[21] They specified the revival was being treated as "Phineas and Ferb season 5", and that it would take place in the following year after the events of the season 4 finale, "Last Day of Summer", during a new summer vacation.[29] The duo also previewed a musical animatic which introduces the first episode.[21]
Reception
On Rotten Tomatoes, 100% of 9 critics gave the season a positive review.[30]Rolling Stone's Alan Sepinwall declared his relief at the return of something as "funny, optimistic, joyous, and inventive" as Phineas and Ferb".[3]Collider's Aidan Kelley wrote the season retained the same "vibrant animation, well-written characters, and infectious sense of humor", and remarked it didn't need to differentiate itself from past seasons in order to "spread its infectious positivity";[31]The Seattle Times's Chase Hutchinson wrote it was "plenty silly, with knowing gags galore and plenty of ridiculous musical numbers", without losing its ability to derive enjoyment from a solid forumula.[32]ComicsBeat's Tim Rooney wrote that Phineas and Ferb "reclaim[s] its throne as the most fun family friendly entertainment on TV".[33]
Screen Rant's Abigail Stevens and Collider's Kelley both felt the first two episodes were only just adequate enough as a premiere, describing them as "just big enough" to serve as a return so that the series could get on with its formula, and "just a little too safe";[34][31]Rolling Stone's Sepinwall noted the series addressed the "high bar" the earlier episodes set for itself by having Doofenshmirtz admit he was "starting slow" with his -inators and the titular duo insisting they could top themselves this time around;[3] and The Seattle Times's Hutchinson wrote that the season "settles back into comfortable comedic rhythms", while "playfully" acknowledging it has a "lot to live up to".[32]ComicsBeat's Rooney felt the first half of the premiere was a show of confidence while the second was a bold display of emotion and drama reflective of the collective confidence of the series's staff.[33]Collider's Kelley and Rolling Stone's Sepinwall both noted the 2015 ending of the series's story as the characters embarked to college, and agreed the series needed to be innovative to justify its existence in the time between then.[31][3]
Stevens felt Doofenshmirtz's return to evil was the worst character regression,[34]ComicsBeat's Rooney recognized the writing's self-reflexive-ness in returning the villain to his hero, Perry,[33] while Collider's Kelley hailed him as the standout, praising what they guessed was "stellar improvisational humor" from Povenmire and opining his dynamic with Perry was the best amongst the series's dynamics.[31]Rolling Stone's Sepinwall compared the focus on the series's supporting characters to that of the fourth season, and pointed out episodes that expanded upon previously established plot points, such as Stacy's knowledge of Perry being a secret agent and Buford having life-size molds of the main cast;[3]ComicsBeat's Rooney praised the cast for "effortlessly" returning to their roles, singling out Martella for sounding the same in his 30s as he did during the original run.[33]
Stevens noted the signs of Phineas, Ferb, and Candace growing up despite the "debatable" idea of the series having character development during its floating timeline.[34] She further opined the subsequent episodes were slightly inferior in quality to the original run, nonetheless praising the inventions, and the "snappy" and "dynamic" musical numbers.[34]Rolling Stone's Sepinwall admitted he saw nothing save one exception in the five episode sampler he watched that he felt could stand up to the original run's best, but lauded the series's ability to return after so long and still feel like itself as a "remarkable achievement".[3]The Seattle Times's Hutchinson wrote despite it not breaking much new ground, it still was "breath of fresh air" and its message of creativity was an amiable effort towards young people.[32] Stevens praised the lessons about family, friendship, and creativity amongst the "small bits of growth very subtly laid out" she could see the makings of.[34]
