Ralph required a tramp handpuppet for their viral for Adult Swim. Amazingly you can't buy such a thing. We bought a very nice puppet of a granddad called Ernest and I set about making him look rancid. I also had to make a spare arm that could be filmed being injected with smack. As you do.
Made while working out of Ralph, using felt, cotton, paint, elastic, string and a plastic bag.
