The Land Before Time III: The Time of the Great Giving - 1995

Littlefoot and his friends are always being bullied and browbeaten by three teenaged dinosaurs: Hyp, a Hypsilophodon. Nod, a Nodosaurus. A Muttaburrasaurus, and Mutt. But as soon as a shower of meteorites (flying rocks) impacts near the Great Valley and causes some stone slide from the Mysterious Beyond, that blocks the water supply of the Great Valley, Hyp, Nod, and Mutt are no longer the biggest concern of Littlefoot and his friends. The lack of water causes battles between the inhabitants of the Great Valley, who've lived in peace and harmony.
