Barb is Chester V's talking and lipstick wearing orangutan with a human brain.
She is a short, obese anthropomorphic orangutan with purple skin, long arms, short legs, and orange fur covering most of her body except her face, hands and feet, and she has shoulder-length orange hair which she keeps tied in a ponytail. Her outfit consists of an orange vest similar to the one her master Chester V, and the Thinkanaughts wear. When she becomes one of Flint's friends she removes the vest, this is done so a few moments after Sam says, "If he really was your best friend, would he call you... monkey?"
