The famous entertainer from The Simpsons has a rat problem in this platforming puzzler. The player must solve each of the fun house’s 60 levels by carefully maneuvering the violet vermin to a manned rat trap somewhere in it, waiting to destroy them one by one. Falling too far or being hit by roaming enemies damages Krusty, who fights back with limited pies or SuperBalls; when the player runs out of lives, the game is over.
