Plot

Greg Heffley is expecting a surprise birthday party, thinking that a pie-baking contest his mother is attending on the same day is fake. When he attends, he discovers that the pie-baking contest was real, and that his whole family has forgotten it was his birthday. After the incident goes viral, his parents are shamed by social media and are guilted into throwing him a "blowout" party which Greg plans to maximize for as much presents as possible. Before the party, Greg discovers that a misprinted "MicroCreatures" (a parody of Pokémon) trading card exists, depicting a three-eyed "Theeble", and is worth a lot of money, even having an online group tracking it down. As the party gets closer, he discovers that the card was shipped close to where he lives, meaning that he might actually have a chance of obtaining it. The party ends in disaster thanks to a deer living in the unmowed grass next door, but Greg ends up getting the trading card that he wanted, only to realize that it is no longer rare, due to popular demand. He still tries to cash on it as his is an original copy, but it turns out that Manny, his younger brother, drew graffiti on it. However, after a new kid's father recognizes Greg and asks him to host his child's birthday party, Greg accepts and manages to start a successful party-hosting side hustle.
