Plot
Bugs Bunny pops out of his hole to clear snow when he's almost hit by Daffy Duck playing as Ebenezer Scrooge in a gas-guzzling SUV. Daffy owns the Lucky Duck Superstore, a megastore like Costco, and treats employees poorly, ignoring Bugs' scolding for Playboy Penguin. Daffy tries to steal charity money collected by the characters like Egghead Jr., Henery Hawk, and Barnyard Dawg. He struggles with his hover scooter and gets beaten up by employees and customers after insulting them. Daffy openly hates the holidays, and Bugs warns him about consequences, referencing A Christmas Carol , and calls him "Bah, Humduck!" Daffy adopts this catchphrase.
After working his employees to the bone on Christmas Eve, Daffy expects them all back at 5:00 AM on Christmas Day so he can capitalize on last-minute shoppers. Assistant Manager Porky Pig (in a Bob Cratchit-like role) pleads with Daffy to let him go home for Christmas and spend time with his daughter Priscilla (in a Tiny Tim-like role), but Daffy refuses.
Later, Daffy's deceased business idol Sylvester the Investor appears, chains as punishment for greed after a disgruntled employee ran him over nine times with a forklift. Sylvester warns Daffy that if he doesn't change his ways, he will share his fate, but also says three ghosts will visit him. Daffy, thinking this is a trick by Bugs, dismisses Sylvester's warning. Afterward, Daffy declines Elmer Fudd's vacation request, Marvin the Martian's trip home, and Porky Pig's wish to visit his daughter Priscilla and her doll, which Daffy tripled the price for. That night, everyone goes home, and Daffy ends up trapped in the store with Bugs by a snowdrift.
Daffy locks himself in his vault to sleep safely, but the Ghosts of Christmas Past (portrayed by Granny and Tweety) appears, taking him back to his childhood at the Lucky Duck Orphanage, where he was ignored every Christmas, explaining his unhappy demeanor and how his store got its name. The Ghost of Christmas Present (portrayed by Yosemite Sam) then appears, scolding Daffy for mistreating his employees and warning him that if he doesn't change, his future will be bleak. The ghost shows Elmer Fudd sleeping on the street due to Daffy's workload, Marvin grieving his inability to visit his home planet, and Porky with his daughter Priscilla. Daffy begins to feel emotion, not guilt, and pleads with Bugs to hide him from the final ghost. After a reenactment, Daffy is left alone with the Ghost of Christmas Yet to Come (portrayed by the Tasmanian Devil).
The Ghost shows Daffy his future, revealing his greed caused his death. At his grave, Porky tells Priscilla that Daffy tried to name himself heir, which was illegal, forcing the Lucky Duck Superstore to close and employees to lose jobs but enjoy Christmas with family. Priscilla, staying longer, confesses she never hated Daffy and understands loneliness during holidays. She promises to visit his grave every Christmas, leaving cookies. Her kindness melts Daffy's coldness, and his heart breaks when he realizes his greed hid his true wish for family. Daffy vows to be kinder as the Ghost of Christmas Yet to Come departs.
Returning to the present, he begins reparations by waking Elmer, promising him a paid vacation. He makes Porky store manager, gives Marvin a rocket to Mars, hires Playboy Penguin, and gifts his employees, offering raises and vacations. He briefly worries about recovering costs, but it fades when Priscilla calls him "Uncle Daffy", fulfilling his wish to belong. The Ghosts of Christmas watch happily, pleased with their success.
Porky and Priscilla finish the movie by saying Porky's famous line: "T-T-T-That's all folks!"
