Donnie Thornberry was discovered in the Congo by Nigel and Marianne as they did a show about orangutans. His parents killed by poachers, Donnie was raised by the gentle primates since he was a toddler. When the Thornberrys came along, his orangutan mother decided that they would be a good family for the boy. Donnie has a lot of energy and is hard to control. He is mostly peach. He is often put into the care of Debbie, who finds her little brother to be quite a handful. Donnie will eat practically anything and enjoys speaking in his unique form of gibberish and doing "The Wedgie Dance".
