Yogis Gang (1973)

Yogi and the gang visit Ranger Smith and put a show for a bus full of orphan children visiting Jellystone Park. Unfortunately, Wally Gator doesn't have any talents and has to be a curtain puller. An entertainer named Hilarious P. Prankster, as a revenge for being refused by Yogi to be in the show, tricks Wally by offering to make him a comedian. As a result, Wally starts playing mean pranks on everybody and starts losing his friends, until they learn Hilarious is behind Wally's new hobby.
