Gui is Tchimpounga’s miracle chimp! Gui’s mother, Golfi, has been living at Tchimpounga for 12 years. As with all the female chimps, Golfi was on birth control. Even so, she became pregnant and is a loving mother to Gui. All the chimps play with Gui and give him rides on their back — even the adult males treat him with care and play with him sweetly.
