Koko the gorilla is a resident at the Gorilla Foundation in Woodside, CA and communicates understands spoken english and uses over 1,000 signs to share her feelings and thoughts on daily life. After the first call about Robin’s passing, Koko came to Dr. Patterson with an inquiring look on her face. Dr. Patterson explained that ‘we have lost a dear friend, Robin Williams. Koko was quiet and looked very thoughtful, Koko signed the words for “woman” and “crying.” Koko became very somber, with her head bowed and her lip quivering; she was crying over the loss of her friend.
"Robin made Koko smile — something she hadn’t done for over six months, ever since her childhood gorilla companion, Michael, passed away. Not only did Robin cheer up Koko, the effect was mutual, and Robin seemed transformed — from a high-energy entertainer, into a mellow, sensitive, empathetic guy, who also happened to be really funny." -Dr. Patterson
