REDWOOD CITY, Calif. — Koko the Gorilla mourned when she learned Robin Williams had died, according to the Gorilla Foundation.

Williams was invited to meet Koko back in 2001. Koko is a gorilla who communicates in American Sign Language.

The two reportedly hit it off well. A video of the two meeting has been released to honor Williams’ memory.

Koko was with Dr. Penny Patterson and Dr. Ronald Cohn when news broke Monday after Williams’ death.

Dr. Patterson told Koko that, “We have lost a dear friend, Robin Williams,” according to the organization.

Koko went quiet and went to sit alone. At the end of the day, Koko became very somber, with her head bowed and her lip quivering.

In the video, Williams met Koko and made her smile — something she hadn’t done for over 6 months.

Koko had been mourning her lifelong gorilla companion, Michael, who had passed away at the age of 27.

In the video, you can see Koko identify Williams from a movie she watched, after putting his glasses on her face. The two got into a very competitive tickle fight as well.

Koko has been known for showing human-like emotions. One video online shows the gorilla “crying” through sign language while watching the sad part of a movie.

Williams died of an apparent suicide at his home near Tiburon, Calif. last week. The beloved actor was remembered for his career in both stand-up comedy and feature film acting.
