Eugene (Muppets Tonight)
From Muppet Wiki
Eugene is an animal character who first appeared in the direct-to-video Muppet production Muppet Classic Theater. He upstaged the other characters by dancing frantically during the "Gotta Get That Name" musical number in the "Rumpelstiltskin "segment. Steve Whitmire revealed on alt.tv.muppets that "Brian Henson performed the mink in 'Gotta Get That Name'".
He received the name "Eugene" on Muppets Tonight (usually performed by Steve Whitmire), where he worked in the control room alongside Nigel.
His precise species is never identified on screen, but his resemblance to Maureen the Mink and Whitmire's comment of the puppet being that of a mink causes most fans to belive Eugene is a mink.
In a Muppet Central interview, Steve Whitmire said that Eugene was his favorite new character from Muppets Tonight.
