Ghost of Dragstrip Hollow

After being evicted from their old clubhouse, members of a Los Angeles drag racing club move into an old deserted mansion and set up shop, making it their new headquarters. For the club's grand opening, they hold a Halloween masked ball and invite everyone to come dressed as their favorite monster. The festivities take an unexpected turn when one of the youths discovers an imposter among them: a real live monster (AIP's oft-reused She-Creature costume, played by its real-life creator Paul Blaisdell), who has been mixing in with the kids, hogging all the dances with the best-looking girls. The phony monster is unmasked at the end of the film by one of the teenagers, revealing it to be AIP's special effects maestro Paul Blaisdell.
