Behemoth is an orange monster who first appeared on "The Muppet Show".

A notable moment for Behemoth was the musical number "Under My Skin", during which he tried to eat Shakey Sanchez while singing the song.

He first appeared in the Sandy Duncan episode, where he was a full-body character for this time and had black eyebrows instead of brown ones. His name was mentioned in the Don Rickles & Coolio episode of "Muppets Tonight", in which he was Ernst Stavros Grouper's assistant.

Behemoth has been performed by Richard Hunt (in the Vincent Price episode), Dave Goelz (in the Candice Bergen episode), Jerry Nelson (in the Zero Mostel episode) and Bill Barretta (Muppets Tonight)
