Jabba the Griffin is mentioned as Chris's great-great-uncle in "He's Too Sexy for His Fat" when Peter points out that Chris comes from a long line of "husky" Griffins.
He utters what sounds like "Rasha Naba Doe-ah Gola Wookiee Nipple Pinchy!" and resembles Peter. Princess Leia is seen as his slave.
Jabba the Griffin is voiced by Seth MacFarlane.
