Caleb Siles

From Muppet Wiki

Caleb Siles is one of the villains in The Muppet Musicians of Bremen. He is a part of a gang of thieves, along with Mordecai Sledge, Lardpork and Mean Floyd. He is the only group member who is not a farmer; he is more interested in money. He originally owned Catgut.

As the old Henson.com "Featured Creature" page explains, "Caleb was part puppet and part costume. In long shots, the character's head was worn as a mask by a performer inside the costume. In close-ups, he was manipulated like a hand puppet." The illusion was so convincing that the Muppet Workshop received a phone call from a Hollywood makeup artist who was convinced that Henson had discovered a new form of makeup.
