Scooby-Doo and the Ghoul School is one of the animated movies in the Hanna-Barbera Superstars 10 series. Shaggy, Scooby-Doo and Scrappy-Doo are athletic directors at a school for the daughters of classic monsters.
Shaggy, Scooby-Doo and Scrappy-Doo have been hired as athletic directors at what they think is a finishing school for girls. After meeting the headmistress, Miss Grimwood, the trio discover that it's actually a school for ghouls, and the students are the beautiful daughters of classic monsters.
After the girls win a volleyball match against the neighboring boys' military academy, the wicked witch Revolta sends her Grim Creeper out to abduct the girls. Shaggy, Scooby and Scrappy go to the rescue, accompanied by the military cadets.

- For some reason, the trailer for Warner Home Video's VHS and DVD releases of this movie mostly used clips from Scooby-Doo on Zombie Island, Scooby-Doo and the Witch's Ghost, and Scooby-Doo and the Alien Invaders, as if to make it look as if Velma, Fred, and Daphne are in this movie.
