Scooby-Doo (character), Shaggy Rogers, and Scrappy-Doo are on their way to a Miss Grimwood's Finishing School for Girls, where they have been hired as gym teachers. Once there, however, they find that it is actually a school for girl ''ghouls''. The pupils include Sibella, the daughter of Count Dracula; Elsa Frankenteen, the daughter of Frankenstein's monster, Winnie, the daughter of the Larry Talbot; Phantasma (usually called Phanty for short), the daughter of a phantom, possibly the Erik (The Phantom of the Opera); and Tanis, the daughter of the Kharis – all parodies/tributes to the Universal Monsters of the 1930s–40s. Other residents of the school are a floating white hand; an octopus, who is the school's butler; Legs, a spider that helps with the upcoming volleyball match; Miss Grimwood, the headmistress; and her pet dragon Matches (who dislikes Scooby at first, but later becomes friends, and has a strong friendship with Scrappy). Shaggy and Scooby want no part of this at first, but eventually they agree to stay as teachers.
