Boppity
From Muppet Wiki
Boppity, a blue frackle, was one of Cosmo Scam's henchmen in The Great Santa Claus Switch.
The puppet used for Boppity would be reused in later productions as a generic utility monster. The puppet, known as the Blue Frackle, would change performer, attire, role, name and even gender depending on the production needs.
