In both the original series and its reboot, Wembley is one of the five main characters, and the best friend of the show's protagonist Gobo Fraggle.

[5] During the audition process for Fraggle Rock, fellow Muppeteer Jerry Nelson (later to play Gobo) performed Wembley.

Wembley's puppet has the unique ability among Fraggles to roll his eyes, often used in scenes to show that he is growing nervous or excited.

He also appears in Fraggle Rock: The Animated Series, voiced there by Bob Bergen.

Along with the other Fraggles, he appeared (performed by Steve Whitmire) in the 1987 TV special A Muppet Family Christmas.
