Dear Koko Fan,

In the above video, Koko’s curiosity and love for exploration shine as she engages with clay, using all her senses to examine it.

This clip shows how she retained signs (like “clay”) even if she didn’t use them often, demonstrating her remarkable memory. Providing her with novel objects and experiences like this helped us learn about her unique preferences and behaviors.

The session ends with Koko’s signature flair—a playful toss!

Koko’s willingness to try new things — and be so lovable — shows us that great apes are so much more than what we humans expect them to be.
