His first appearance comes in the episode "Capture the Moon." He usually repeats everything the World's Oldest Fraggle says before the World's Oldest Fraggle has a chance to say it, followed by a scold and usually (unless avoided) a knock on the head.
One of his larger roles occurred in the final season episode "Inspector Red." He steals the Fraggle Horn so that there can't be any more meetings (to limit the occasions when World's Oldest would strike him).
