Pushmi-pullyu

From Muppet Wiki

The Pushmi-pullyu was built by the Jim Henson Creature Shop, along with 94 other animatronic animals, for the London West End musical Dr. Dolittle.

The Pushmi-pullyu was also seen briefly in the film version of Dr. Dolittle, one of only a few references outside the main story concept that was lifted from the original stories by Hugh Lofting.
