The Rainbow Valley

Roger Ranger is taken captive by the elephants when he asks them for passage through their graveyard to get to a place known as Rainbow Valley. If Kimba wants him back, he and a few other animals must swim in a swamp, where if you stop moving you'll drown, for 10 days without stopping for anything. While doing this, Kimba recaps the events of how he first met Roger Ranger long ago.
