Carter

From Muppet Wiki

Carter is Howard Tubman's elderly, doddering butler seen in "The Tubmans of Porksmith" and "Boarshead Revisited" sketches on Muppets Tonight. Carter also appeared in Muppets from Space, as a resident of the Muppet Boarding House.

The puppet was later recycled as Faversham, Miss Piggy's butler, in an appearance on Donna's Day.
