The Adventures of Jimmy Neutron: Boy Genius: Attack of the Twonkies is a video game based on the episode "Attack of the Twonkies" from The Adventures of Jimmy Neutron, Boy Genius. It was released for the PlayStation 2, Nintendo Gamecube, and Game Boy Advance by THQ in 2004.
This game provides examples of:
- Adaptation Distillation: The game cuts Libby's subplot where she petitions for Graystar to perform at the school and just has Principal Willoughby announce that they're already hired to perform.
- Adaptation-Induced Plot Hole:
- Even though nobody keeps them as pets in this game, the setup to Carl wanting to keep one (in which he goes to the pet store and finds out he's allergic to all of them, where he doesn't have the same reaction to the Twonkie) is still kept in the game despite lacking any plot significance in this context.
- Similarly, in the original episode, Sheen's Twonkie is the only one that never mutates because of his bad singing, setting up the Something We Forgot gag at the end. Since nobody keeps the Twonkies as pets in the game, this gag never properly gets set up yet remains in the end cutscene.
- Adaptation Expansion: The video game is basically an extended version of the original episode, and even features locales that don't appear in the episode like Retroland. The game also introduces the ability to de-morph the Twonkies back into their "cute" form, where in the original episode the mutation was permanent and the only effect bad music had was putting them to sleep.
- Adapted Out: The game skips over the part of the episode where all the kids adopt Twonkies as pets and cuts right to them growing monstrous to the sound of good music. The Twonkies also still are able to multiply in this form too. The entire B-plot with Hugh buying a dummy is also completely absent.
- Ascended Extra: Though not quite promoted to being a major part, the One-Man Band from the original episode that was used for an extremely brief gag becomes a citizen in need of saving at one point during the game.
- Demoted to Extra: Libby, Judy and Hugh's roles are reduced due to their subplots in the original special being cut.
- Didn't Think This Through: In the park level, at one point Jimmy has to get down one of the giant Twonkies from the roof. When he successfully does that, he's at first really glad...until he realizes he's now in harm's way.
- The End... Or Is It?: Just like in the original episode, Sheen's stray Twonkie is forgotten about at the end and left to run free.
- Final-Exam Boss: The final boss takes snippets from all three of the prior boss fights and turns them into one fight.
- Game Within a Game: The arcade in Retroland features five of these, all obvious homages to already existing arcade games note , that Jimmy must play and top the high score in to win.
- Joke Item: Many of the gizmos Jimmy invents actively harm him or cripple the player in some way, like shoes that make him as if he's walking on ice or a bad combination of food that stuns and sickens him for a bit.
- Mission Control: Jimmy gets hints from Vox in the game.
- Musical Assassin: "Assassin" isn't the right word here, but Jimmy actually weaponizes Sheen's singing voice in this game as a way to de-morph the Twonkies.
- Not in the Face!: Principal Willoughby says it as Jimmy's mini comet twirls around him.
- Raster Vision: Shows up in all of the games you play in the arcade in Retroland.
- Silliness Switch: While some of the gizmos you can invent have actual utility like the one that stops you from sliding on ice, most of them fall under this category, like one that temporarily changes Jimmy's hair and another that makes the screen flash random colors.
- Slippy-Slidey Ice World: The frozen lake and the final boss both take place entirely on ice.
- Something We Forgot: As was the case in the original episode, the Twonkie Sheen left in his bag elicits this reaction out of Jimmy at the end.
- Weakened by the Light: The Retroland boss is a case of this; he must be defeated by opening holes in the ceiling for letting light in.
- Weapons That Suck: Jimmy uses a vacuum weapon to suck up the Twonkies.
