Gorillas are our closest living relatives in the animal kingdom. The apes generally inhabit Africa's jungles from Cameroon to Rwanda, but one is seen living outside Caveland in Ook and Gluk: Kung Fu Cavemen from the Future. After Ook and Gluk trap Mog Mog in a tar pit, they decide to free her. They go to gorilla caves and begin to tease one of them. This enrages the gorilla and it chases them. The boys begin to scream more names at it and it proceeds to knock down the tree and walks onto it to grab the boys. Mog Mog then orders the ape to release the boys. She then roars at the ape and it runs off. After that, it is not seen for the rest of the book.
