Help!...It's the Hair Bear Bunch!

Help!...It's the Hair Bear Bunch! was a Saturday morning cartoon, produced by Hanna-Barbera Productions in 1971 for CBS.

The series depicted three fun-loving hippie bears — the Afro-ed Hair Bear, confusing-talking Bubi Bear, and laid-back Square Bear — who always find a way to escape the Wonderland Zoo and go out on adventures. Trying to stop them are the head zoo director, Mr. Eustace P. Peevly, and his hopelessly inadequate assistant Lionel J. Botch.

Other residents of the Wonderland Zoo include Bananas the Gorilla, Furface the Lion, Pambo the Elephant amongst others

The bears have a modern "bachelor pad"-styled den at the zoo, but they disguise it from Peevly and Botch to avoid revealing their comfortable surroundings. The bears also have an invisible motorcycle, which Square Bear can call upon when necessary by jumping in the air and kicking his leg to start it. The motorcycle is never explained, though Hair Bear has commented that he doesn't know how Square does it, but is glad that he does.
