The Land Before Time III: The Time of the Great Giving

When a meteorite cuts off the dinosaurs' water supply in the Great Valley, Littlefoot and his friends go on an adventure in search of another source. There's a pool near the Mysterious Beyond where the treacherous Sharpteeth live, and the youngsters must dodge all kinds of danger -- bullies, fire, velociraptors -- to get to it. But, with songs in their hearts, they all work together and save the day for their peaceful village. (official distributor synopsis)
