Peepo is a Veetanho who own the mercenary pit Peepo's Pit in Bartertown, Karma-IV.
From the Books: "'Whom do we have here?' Jim’s translator spoke as a being approached. It was as tall as a human, but had a long body and rather short limbs. It looked for all the world like a short-nosed, white rat wearing huge sunglasses. Its nose was wide and flared as it approached. 'I do not recognize these two humans in my pit.' Jim had been so surprised at the huge dark sunglasses in the relatively dark space that he took a second to realize it was a Veetanho talking to them." - Cartwright's Cavaliers, p. 55.
