Bernice the Warthog

From Muppet Wiki

Bernice the Warthog appears in the "Walrus & Warthog" episode of The Animal Show. She is very proud to be ugly.

The puppet would be reused as Warren the Warthog in the third season episode "Warthog and Baboon," and would later appear on Muppets Tonight. The puppet was also used as Mr. Warthog on Mopatop's Shop.
