You play as Jimmy Neutron in this GBA adventure, fresh off a space trip—except you accidentally brought back some weird little alien pests called Twonkies. They’re multiplying like crazy, and now Retroville’s overrun with them. Typical Jimmy luck, right?

Mostly a side-scroller with some light puzzle-solving—you’ll be jumping platforms, zapping Twonkies with your shrink ray, and fixing gadgets to clear paths. The art style nails the show’s goofy vibe, though the controls feel a bit stiff when you’re trying to line up precise jumps. Still, it’s got that early 2000s licensed game charm—short, silly, and weirdly nostalgic if you grew up with the cartoon.

Fair warning: the later levels get kinda repetitive, but messing around with Jimmy’s inventions (like the hover boots) keeps it fun for a quick playthrough. Definitely one for fans of the show.
