The Vile Bunch refers to the group of Muppets who appear with Alice Cooper during his stay on The Muppet Show in episode 307. Working for an unseen employer set on gathering souls, Alice has brought his own monsters -- a snake, Beakie, Purple Heap, and a monster backup band. The band, which performed with Alice on his hit songs "Welcome to My Nightmare" and "School's Out," was composed of Chopped Liver, Silver Beak, Flower-Eating Monster, a shark-like drummer, and a guitarist.
