Pistachio Eating Caterpillar

Caterpillar (referred to Orange and Pear as the Pistachio-Eating Caterpillar) is a very minor character who only appeared at the end of Mystery of the Mustachios. A pistachio-eating caterpillar was mentioned several times by Orange in the episode. After almost all of the Mustachios were killed, only one remained: Richard, the apparent leader of the Mustachios. By the warnings of Orange and Pear, the real pistachio-eating catepillar arrived and ate Richard. He then coughed up Richard's fake mustache, stating that he hated it when the Mustachios didn't shave.
