Role in the special
After losing the Riddle Race, Clyde along with Dottie and Joey left Stoney and joined Wilma's "Just Say No!" club, in which Stoney was discovered to have the drugs by Officer Bob Quartz and taken to the police station. Later during a concert with Michael Jackstone, it was shown that Clyde, Freddy, Barney, Betty and Philo and the others also attended, suggesting that they got their own tickets.
