The Skatebirds, so-called because they roller skated, were named Satchel (a pelican), Knock-Knock (a woodpecker), and Scooter (a penguin). Their nemesis was Scat Cat, voiced by Scatman Crothers who had previously played Hanna-Barbera's Hong Kong Phooey. The appearance of the characters and the format of the show was similar to Hanna-Barbera's Banana Splits.
