From Muppet Wiki
Beavers have been featured in several Muppet productions.
Harvey Beaver stared in Emmet Otter's Jug-band Christmas which also featured some unnamed background beavers.
Beavers were part of the Forest Animals seen from time to time in the later seasons of The Muppet Show.
A beaver, performed by Jim Henson, debuted on The Muppet Show in episode 217, where he cut down the flagpole where Gonzo was playing the bagpipes to Eine Kleine Nachtmusik.
Beavers were also a major topic on Episode 118 of The Animal Show.
