Sopwith the Camel
From Muppet Wiki
Sopwith the Camel was a seven-foot tall Muppet camel who danced with Helen Reddy in The Muppet Show episode 313. He also appeared in the finale of episode 413 and later in episode 518 where he (she) was referred to as "Loretta."
Muppet builder Caroly Wilcox took two weeks to build the Sopwith puppet. It was performed by two dancers, standing up in the costume with their legs acting as the camel's. The front dancer used his arms to control the head.
The name is a reference to a WWI aircraft, the Sopwith Camel.
