In the above video, Penny asks Koko a question and Koko responds by having her plush ape sign the answer.

Koko was always very creative with her signing and her close bond with Penny was the foundation for Koko’s language learning success.

Using language as a tool, Penny was able to gain insight about Koko’s thoughts, feelings and motivations. Penny and Koko accomplished groundbreaking work together, and also had a lot of fun.
