Dr. Papanak is a hand puppet that appears to be living. It is unknown if it is just one of Salad Fingers' hallucinations or if it really is a sentient being. Dr. Papanak has so far only appeared in episode 10. He seems to be wild since he bit Salad Fingers on the head and attacked a horse. He appears to have sharp weapons that emerge from his hand-hole at will. He uses these to cut through a horse falsely named "Horace Horsecollar". It is unknown why Salad Fingers used Dr. Papanak to operate on the horse instead of Harry (Milford Cubicle). Salad Fingers refers to Papanak as if he has seen him before.
Dr. Papanak is found buried under some other random objects in a cart; the reason he is there is unknown. His only form of communication appears to be raspy grunts and low growls. It is unknown whether he is a sadist or simply enjoys eating flesh/blood.
Dr. Papanak is a pale hand puppet with a blue suit and a tie. He has a head mirror and metallic claws instead of fingers.
- Dr. Papanak is a very violent humanoid creature.
