Quongo

Quongo the Wild Mountain Gorilla was created for The Muppet Show episode 219, where he teleported back from Africa with a startled Kermit.

He can also be seen in episode 320 throwing coconuts during "Hawaiian War Chant."

When he appears in a jungle scene performed by Jerry Nelson in episode 324, he's referred to by Kermit simply as "chimp."

Quongo received his name in episode 509, where he was booked to wrestle Gonzo. He was performed by Richard Hunt in that episode.

When he appeared in episode 513 to sing "I've Got a Lovely Bunch of Coconuts," he was again performed by Jerry Nelson.

He appeared in a Muppet Meeting Film: "The Five Basic Rules of Selling", where he got into a struggle with Leo. Here he was played by Frank Oz.

Quongo hitches a ride with the rest of the Muppet gang in "The Muppets Go Hawaiian" View-Master set.
