Log

From Muppet Wiki

The Log appears in the Sesame Street "Monsterpiece Theater" production of "Twin Beaks." The property of the Log Bird, the log is able to talk, but cannot answer the question of why the town is called "Twin Beaks." Agent Cookie marvels at the wood's linguistic abilities, and thus insults the Log Bird.

The puppet would later be recycled as a Whispering Log in the Mopatop's Shop episode Musical Sounds.
