Fred decides the best way to solve the mystery is to enter the contest as a band in order to drive the Yowie Yahoo to capture them. While they are practicing (but not very well), a golf cart approaches them. In it are Jasper Ridgeway, a snotty manager, and his band, the Bad Omens. They criticize the gang's playing and make them leave the stage so they can practice. Then the gang learns that Jasper was once the manager of Wildwind. The gang grows suspicious of Jasper and thinks he might have put his band up to masquerading as vampires and getting rid of all the other performers. They split up, with Fred, Velma and Daphne going to Jasper's trailer and Shaggy and Scooby staying at the food stands.
