However, the spell was miscast - causing all of the monsters to shrinking in size. sends out his henchmen, led by Spring Heeled Jack, Bigfoot, Kraken, Gremlin, and Medusa while Vampire and The Monster are watching TV in the Miles home. They must fight their way through the upstairs and kitchen of the home, the street, and the sewer; they emerge in a construction site and an Orientalist garden before fighting Warlock at Monster Mountain, although that's not the end of the game.
