In the frightening, maze-like dungeon laboratory deep within Castle Grotteskew, mad scientist Professor Erasmus brings his bizarre experiments to life. His first creation, Stitch Head, has long been forgotten.  But when a traveling circus ringmaster promises to make him a star, Stitch Head is torn between his almost-life in the castle and the promise of fame outside its walls. Before he can decide what to do, Castle Grotteskew and its inhabitants (living and almost-living) are in danger: the professor's latest monstrous creation has smashed its way to freedom, and Stitch Head may be the only one who can stop it.
