Picklepuss and Pop

From Muppet Wiki

Picklepuss and Pop are a cat puppet duo created by Caroll Spinney in 1967 for the Boston broadcast of Bozo's Big Top.

In 1988, the puppets were rebuilt as Muppets by the Muppet Workshop and featured in the Jim Henson Play-Along video, Wow, You're a Cartoonist!. In this appearance, Picklepuss is a Hand-Rod Muppet, and Pop is a Full-Bodied Muppet.

Spinney has subsequently made live appearances with the Muppet version of his Picklepuss character.
