Muppets that should come back

[Rugby]

What about the piano player guy that bangs his head on the keys when he gets writer's block? I'd also like to see the shifty guy in the trench coat that tried selling Ernie an O. It would be neat seeing Herbert Birdsfoot again and Sam the Robot. I'd also like to see that light blue monster with the bushy eyebrows over the eyes, no nose and kind of a big mouth.
