Pinocchio (Muppet Show)

From Muppet Wiki

Pinocchio is the Muppet version of the fairy tale character of the same name who appears in episode 508 of The Muppet Show, in which he sings the opening number, "Puppet Man," to Geppetto, as played by Pops. Pinocchio also appears in the "Veterinarian's Hospital" sketch later in the episode.

In the interviews included on the Fraggle Rock: Complete First Season DVD set, Steve Whitmire refers to his Wembley Fraggle voice as "Pinocchio's voice," which was a voice he used often during his first years of performing with the Muppets.
