The evolution of Floyd Pepper.

Image As seen in / Year Notes

The Muppet Show pilot
Season 1
(1975 - 1977)
The first Floyd Pepper puppet closely adheres to Michael Frith's original design (seen below). The design notes mention "lenticular eyes", an effect that was only used in one shot during the "Love Ya to Death" musical number in The Muppet Show: Sex and Violence.

In the first season of The Muppet Show, Floyd retains his original Sgt. Pepper outfit but occasionally wears a tux (without his hat) when playing in the orchestra. By this time, the colors of Floyd's skin and hair have paled with age.

Floyd's lower jaw is reshaped, leaving him with a less rounded chin and a more rounded lower lip. His foam skin is now covered in lavender fleece. His most regularly worn outfit, starting with a Muppetism and up to the Studio DC: Almost Live specials, is a blue jacket with a dark gray undershirt.

Floyd's nose shrinks slightly and becomes more red. He switches to an outfit closely resembling his original costume, and occasionally wears a more casual green and black checkered shirt.
Design sketch by Michael Frith
This original sketch shows Floyd donning a blue nose and outfit, both of which were changed to red tones in puppet form. He was further designed to appear with a more decorated hat and a gold earring.
