Scooby-Doo and Shaggy learn there are things even scarier than homework in this feature-length field trip into mystery and mayhem! The academic adventure begins when the boys sign on as gym teachers at Miss Grimwood's School for Ghouls -- only to discover the pupils are (zoinks!) daughters of the world's most frightfully famous monsters! But when the girl-ghouls are kidnapped by the evil Revolta and her spider-bat flunkies, our heroes spring into action to rescue their fiendish little friends in spectacular Scooby-Doo style!
