Big V

From Muppet Wiki

Big V was a long-nosed Muppet monster who ate Kermit in the classic "Inchworm" sketch, performed on The Ed Sullivan Show in 1966. This was done again in The Muppet Show, but with Gorgon Heap in his place.

Big V also swallowed Mack in a Southern Bell Telephone ad in the late 60's. He also portrayed the title character in Shrinkenstein and had a cameo in Hey Cinderella!.
