Like any red-blooded American female, Koko gives herself regular manicures, though Penny usually does the clipping part for her. In this photo, Koko takes time out from watching one of her favorite cooking shows to finish filing.
You can see a short video clip of Penny and Koko doing nails together on KokoTV entitled “Nails, Nails, Nails” (scroll down to “Gorilla Care and Grooming” and make sure you have Quicktime 6 or higher – or get the free Quicktime download by clicking this link).
