His origins are described quite simply as "tomboy". That was in 1976, when he was just two years old. That's when he suffered the same fate as the other baby monkeys. Bullets flew through the air, a crate lid slammed shut - off to the laboratory. In 2002, he moved with the others from the animal experiment into the monkey house. 26 long years of his life were simply erased. His motor skills are limited - hence his difficulty in climbing. This makes the other chimpanzees in his group all the more cautious when dealing with him. He hardly climbs trees and has a strange gait on the ground. Gogo is learning to come out of his shell more and more, whether playing, making physical contact with others or arguing within the group.
