Plot
Scooby-Doo, Shaggy, and Scrappy-Doo are on their way to Miss Grimwood's Finishing School for Girls, where they have been hired as gym teachers. However, once there, they find that it is actually a school for daughters of paranormal beings. The pupils include Sibella, the daughter of Count Dracula; Elsa Frankenteen, the daughter of Frankenteen Sr.; Winnie, the daughter of the Wolfman; Phantasma (usually called Phanty for short) the ghostly daughter of a phantom; and Tanis (named after an Egyptian city), the daughter of the Mummy–all inspired by Universal Monsters of the 1930s-40s. Other residents include a floating white hand; an octopus butler; a two-headed shark that lives in the school's moat; Legs, a spider that helps with the upcoming volleyball match; Miss Grimwood, the headmistress; and her diminutive pet dragon Matches. Frightened by this, Shaggy and Scooby are initially hesitant, but they ultimately agree to stay as gym teachers.
At the annual volleyball match against the boys of the neighboring Calloway Military Academy, the boys rig the volleyball with a remote control, but Scooby accidentally swallows the remote and allows the girls to win instead.
The girls' fathers come for an open house party on Halloween night. Though Scooby and Shaggy fear being trapped in a house full of ghosts and monsters, the fathers are friendly and polite, and the party is a success. Before leaving, the fathers warn a fearful Shaggy and Scooby not to let any harm come to their daughters, lest they face severe consequences.
