Play Jimmy Neutron Boy Genius - Attack of the Twonkies (U)(Venom) Online

Jimmy Neutron Boy Genius: Attack of the Twonkies came out for the Game Boy Advance in 2004, published by THQ. It was one of those licensed platformers that felt right at home on the handheld, blending cartoon action with the kind of straightforward level design common in that era. You step into Jimmy's lab shoes, and the game wastes no time throwing you into a mess only a boy genius could handle.

You control Jimmy, navigating side scrolling stages while fending off waves of Twonkies with your shrink ray. The main goal is to clear each area of these pests before they cause too much havoc. Key mechanics include platforming across Retroville's rooftops and interiors, using gadgets like the shrink ray to defeat enemies or solve simple puzzles, and collecting items to progress. The pacing is brisk, though the enemy swarms can make some sections feel cluttered. It captures the show's energy in a way that keeps you pushing through the occasional frustration.
