The Baboons are minor villains from the Disney's 1999 animated film Tarzan.
Role in the film
They are first seen resting in trees when Kala runs across the jungle after hearing baby Tarzan's crying.
Later in the film, Jane Porter meets a baby Baboon and tries to sketch him; however, the Baboon likes the drawing so much that it steals it, and when Jane tries to recover it, she is attacked by the entire troop of adult Baboons. She is saved by Tarzan, who manages to calm the angry primates by returning Jane's sketch to them. They happen to make Jane lose a piece of her dress, her umbrella, her left boot, and her hat.
Later, the Baboons are among the wild animals summoned by Tarzan to fight against Clayton and his men. This implies that they are not really evil but rather extremely short-tempered and vicious, as are Baboons in real life.
