Erin gets a new foster, Rachel, who works as a veterinarian at a rescue station for abandoned monkeys. When a little orangutan named Budi arrives at the station, Erin and Rachel decide to take him home for a few days before they can release him into the enclosure with the other monkeys. Although Erin had some roommates in the children's home, none of them were anywhere near as cute and playful as the little orangutan Budi!
