The Land Before Time III: The Time of the Great Giving
Uh-oh! Trouble comes to the Great Valley in the form of a crashed meteorite that now blocks the main water supply. As the land dries up and the animals begin to go thirsty, the different dinosaurs who once coexisted peacefully become contentious. When bigotry and bickering increase, Littlefoot and his gang decide that it's up to them to save the day -- but first, they must face down Tyrannosauruses and other carnivores.
