She has her own specially equipped trailer and two outdoor play areas. Koko, like all gorillas, builds a nest each night to sleep in. Unlike most gorillas, Koko's nest is made out of warm, soft blankets. She usually brings her stuffed dolls to bed with her. She sleeps for about 10 to 13 hours each night.
Gorillas eat mostly plant foods like leaves, shoots, fruit, bulbs, bark, vines and nettles.
They also eat ants, termites, grubs, worms and insect larvae. Koko's diet includes a wide variety of fresh, organic fruits and vegetables. Her favorites are nuts, apples, gourmet tofu dishes and corn on the cob. Smoky still visits Koko when Penny is there to supervise. Koko is very gentle with her cat.
