Also known as Krusty's Super Fun House.
Rat Trap was developed by Audiogenic and was scheduled for a commercial release, but Acclaim were looking for a game to use with their newly aquired licence for 'Krusty's Super Fun House', and so they purchased Rat Trap from Audiogenic and altered the game by changed the game character to Krusty and the name to Krusty's Super Fun House, and so it became a different game.
