The Glutton

From Muppet Wiki

The Glutton is an overweight, humanoid Muppet who appeared in an Ed Sullivan Show sketch which aired on February 17, 1971. The ravenous gentleman rapidly consumes a beverage, a chicken leg, and a saltshaker, among other items. While cracking nuts, he finds a purple creature inside a nutshell that shrinks him. The Glutton meets an ironic end, eaten by a larger version of himself. However, he joins Jim Henson for a curtain call, and attempts to devour Ed Sullivan.

His appetite and facial design are similar to the later Lardpork character.
