Krusty's Super Fun House has been taken over by a group of rats. You must help Krusty the Clown guide them into trap machines to clear out his home. To do this, you need to use Krusty's environment to create paths for the rats to follow. The objects you can move around include blocks, fans, and pipe pieces.
The trap machines are operated by other Simpsons characters: Bart, Homer, Sideshow Mel, and Corporal Punishment. Your goal is to outsmart these characters and herd the rats into their respective traps.
