Magilla Gorilla was a Hanna-Barbera cartoon that originally ran on television from 1963 to 1967. In an episode entitled “Camp Scamps,” Magilla overhears Mr. Peeples on the phone with the aquarium and thinking that he’s going to be sent away he runs away from the pet store and ends up getting on a bus going to Camp Kitchy Gooney.
Once at Camp Kitchy Gooney, Magilla finds himself in charge of the other campers after the counselor falls off a cliff and gets poison ivy (he puts Magilla in charge because he is the biggest camper). The campers respond as any campers left in charge of another camper would – by creating havoc.
The episode is available on Magilla Gorilla: The Complete Series, which is available to purchase on Amazon (affiliate link).
