Pencilvester the Parasite from Rick and Morty. He is an anthropomorphic pencil who is apparently great lifelong friends with Rick Sanchez and Morty Smith. Rick loves him so much, that he was hesitant to kill him, even when he knew he was an Alien Parasite and had Morty do it for him. Morty also loves him so much, that he refused to kill Rick in front of him. However, he may have only done this to get away from the other alien parasites, to tell him his plan to destroy them.
