In recent decades, the work of performers or designers have altered the mechanics and effect of gorilla suits, often using animatronics, taxidermy eyes, realistic fur, and other aides. Jim Henson utilized typical gorilla suits and even a full-bodied gorilla Muppet in several productions (like in "Time Piece", "The Cube", some episodes of "Sesame Street", and the Avery Schreiber episode of "The Muppet Show"). The person inside the gorilla suit is often uncredited. Jim Henson's Creature Shop has contributed to this development in its own way, through work on "Buddy", "George of the Jungle", and "MirrorMask". Many suit performers of Henson's characters portrayed gorillas in other productions.
