Shuggy is a young vampire who has just inherited an old Scottish castle from his grandfather. He soon realises that the mansion is haunted by countless ghosts, ghouls and other evil spirits. To clear his new home of its undesirable inhabitants, he must venture through the whole castle: from the Dungeon through the Boiler Room and the Gallery (not forgetting the Graveyard), and all the way up to the Clocktower.
