Coconut Monkey is a character in Xenosaga Episode III. Coconut Monkey is Dark Professor's cherished pet.
Coconut Monkeys are a type of monkey that live on Pedea Island on Second Miltia. It has a knob on its head that resembles a palm tree. They possess greater intelligence than chimpanzees and are said to be as smart as elementary school-age human children.
After the player defeats Erde Kaiser Sigma, Coconut Monkey reveals he is actually the Dark Professor. When he fell ill and sensed he was dying, he created a robot (modeled after his actual pet Coconut Monkey) and sealed his mind inside it.
