Kanzi is a very clever ape who can use human language to communicate with people. He can understand thousands of different words and uses special symbols on a computer to tell people what he wants or how he feels. Kanzi is a bonobo, which is a type of ape that lives in Africa, and he has been studying with humans for many years to learn how to communicate. He is special because he can use gestures, sounds, and the computer symbols all at the same time to express himself. Think of it like playing a really cool game where you get to talk to an ape and he talks back to you!
