Diego paddles a dug-out canoe to visit his friend, Burgin, at his Orangutan Reserve in Borneo. Orangutans are really smart and love to play follow-the-leader! Everyone's playing when suddenly, Baby Orangutan gets into Diego's canoe and accidentally floats away! Uh oh! He's headed for some Giant Rocks! Diego and Big Sister Orangutan speed off after him - jumping onto a swinging bamboo branch; helping Baby Orangutan duck under the low tunnels; and taking an elephant ride across the Deep River. Will we get to Baby Orangutan in time?!
