The Land Before Time II: The Great Valley Adventure

In the Great Valley, Littlefoot and his friends feel life is too restrictive under the watchful eyes of their overprotective parents. Wishing not to be treated like babies anymore, the group pursues two dangerous dinosaurs that have stolen an egg from Ducky's nest. When they bring the egg back to the valley and it hatches, the friends are surprised to discover a baby Sharptooth. Rather than abandoning him, they name him Chomper and strive to raise him as one of their own.
