Here’s a nice example of why you would never want to be bitten by a chimpanzee. It may look like Foxie is threatening to kill her troll doll, but I simply caught her in the middle of a yawn.
This photo also shows how chimpanzees – even tiny chimpanzees like Foxie – are able to fit so much food into their mouths. I have seen Foxie stuff eighteen pieces of monkey chow into her mouth at once (each piece is about the size of a walnut in the shell).
