Koko is presented with a small piece of birthday cake by Dr. Penny Patterson (her mentor and friend), while she and Dr. Ron Cohn (her other mentor) sing Happy Birthday to Koko on her 40th birthday (2011). Koko then blows out the candles (one at a time). Sometimes she makes a wish. We at the Gorilla Foundation hope that all of Koko's wishes come true, and it is part of our mission to help make it so.
