Carl has made the sheep wear a mask of Paul's face to make up for his absence. It talks to Carl (although the sheep doesn't speak English, Carl seems to understand it) in a similar to the way Paul used to talk to him. Towards the end of the episode, Carl begins to get increasingly annoyed by the sheep's un-Paul-like behavior, before stating that he will throw it into the blood canal.
The sheep is a guest star in the Llamas with Hats: Hungry for Hands card game. It moves one space backward at the end of each round.
