Slim, a large hillbilly puppet, appeared in The Muppet Show episode 115 where he sang "Put Another Log on the Fire" to his wife. The guitar-playing hillbilly wore a beard, bowler hat, blue jeans and flannel shirt. His head was similar in design to Zelda Rose. The human-sized character was seen sitting in a chair. Although it appeared to be a full-body Muppet, it was not a costume worn by a performer. Henson was crouched down under the seat operating the upper part of the character like a normal live-hand Muppet and rods were used to control the hillbilly's tapping legs. This hillbilly later appeared in issue #2 of The Treasure of Peg-Leg Wilson, in which Kermit calls him "Mister McCoy."
Another country singing hillbilly sang "Ain't Nobody's Business But My Own" with Twiggy in The Muppet Show episode 121. This hillbilly wore a beard, straw hat, blue jeans and a flannel shirt. He was seen sitting on a fence and was operated similar to the earlier hillbilly singer. He had a different head, which was rounder when compared to his more cylindrical headed predecessor; and although he too was performed by Jim Henson, his voice was quite different from the other hillbilly from six episodes earlier.
