However, an unexpected anomaly cuts the Hunch Bunch's celebration short when they learn that Shaggy’s hiccups are forcing him to alternate between human and werewolf. Not noticing Shaggy's transformations into a werewolf, Googie sends Shaggy to a nearby snack bar for something to cure his hiccups, and he attracts horror from the other movie watchers along the way. Scooby, hearing them speaking of a werewolf loose in the theater, hides in a nearby car. The Hunch Bunch attempts to abduct Shaggy, who flees from them, and is then chased by the crowd when they see him as a werewolf. Upon meeting Scooby and seeing his reflection, Shaggy flees the drive-in with his car, Scooby, Scrappy, and Googie in tow, escaping his pursuers with the car's customized features, losing his hiccups in the pursuit and thus remaining trapped in werewolf form. The Hunch Bunch then knocks the group out with moon dust from their vehicle, the "Bat-Copter", and fly back to Transylvania, towing the car.
