Topaz is a Scottish bard who performed on the Muppet Theater Stage in The Muppet Show Comic Book: The Four Seasons #3. He recites his wonder poem "Autumn Mists" (with added moaning) about Glasgow in 1883.
When he announces his poem has seventeen more verses, he is promptly yanked off stage with a shepherd's crook.
He previously appeared in The Muppet Show Comic Book: The Treasure of Peg-Leg Wilson #3, announcing, through a poem, that Miss Piggy's jewels were fakes.
