Fred and Spartan build a trap for the demon, Scooby and Shaggy work to eat all the food in town to lure the demon into the trap, and Velma, Daphne, and Cachinga actually investigate the mystery. They discover the monster to be Francilee Jackson, who was removing the competition to open her own restaurant.
