Aye Carumba! Bart's super hero, Krusty the Clown, is in really bad trouble. Rats have invaded his Fun House.
Is it "sayonara, Krustyland"? No way, man! Bart, Homer, Sideshow Mel, and Corporal Punishment stand armed with the coolest rat traps ever... ever see a rat zapped with 20,000 volts or burst like a balloon?
All Krusty has to do is get the rats to the traps by moving blocks, connecting pipes, finding secret passageways, wrecking the floors and walls, and generally having a great time.
As for the slimy snakes slithering on the floors, the pink flying pigs bouncing around the sky, and the laser-firing aliens, Krusty'll show them some real fun with a barrage of custard pies.
So, before saw-toothed rodents ruin Bart's #1 fun house, and frankly outlandish creatures nail the man who put the "K" in komedy, play this game.
Krusty the Clown needs you... yes, you, you little...
