T.R. is a rooster who first appeared in The Muppet Musicians of Bremen. His big solo number is "Cock a Doodle Blues," sung with a bevy of hens. Although his real name is never given, he offers several meanings for what his initials stand for, including "Tuckered Rooster", "Terrified Rooster," "Travellin' Rooster", "Tender-Hearted Rooster" and "Tough Rooster." Since 2015, the T.R. puppet is on display at the Center for Puppetry Arts as part of their permanent Worlds of Puppetry exhibit.
