Video: Robin Williams's death mourned by a gorilla too
The Gorilla Foundation said that the actor and Koko shared a very special bond after Koko lost her partner. The Gorilla hadn't smiled for six months since his death which is when she met Williams for a video shoot in 2001.
Robin Williams made her smile when both of them ended up joking, wrestling, and even getting into a tickling fight. Her handler said that Koko became silent when he explained to her that Robin Williams was dead.
