Play The Grim Adventures of Billy & Mandy Online

I picked up The Grim Adventures of Billy & Mandy for the Game Boy Advance back in 2006, a Midway release that fit right in with the platform's library of cartoon tie-ins. It was a time when licensed games were everywhere, and this one captured the show's offbeat humor without trying to reinvent the wheel.

You control Billy, Mandy, or Grim across side-scrolling levels, punching and kicking through waves of enemies like zombies and giant chickens. The main goal is to stop an outbreak of rage monsters, which involves navigating screen by screen, breaking objects for health, and using character-specific moves like Billy's clumsy butt bounce. The pacing is straightforward, though some enemy swarms can get chaotic. It feels like a silly, slightly janky brawler that doesn't take itself seriously at all.
