The story centers on a child named Mark who is accosted on his way home from a baseball game by a winged, gargoyle-like alien monster named Bert who requests his assistance in ridding "evil monsters" from his home planet. Mark is reluctant to help, but Bert insists, saying that Mark can use his "weapon" (the baseball bat in his hand) to fight enemies. He quickly whisks him away, and inexplicably fuses with Mark while in flight. This bizarre plot introduction sets up a game that is filled with variations on many traditional horror characters and themes (sometimes with ironic twists) as well as relatively novel, and always weird, characters all its own. Some traditional horror bosses the game features include a mummy, giant spiders, zombies, Medusa, and Death; persistent players will also encounter such creatures as a haunted well that throws plates, a large caterpillar, walking pants, and a huge cat that hurls small kittens.
