The Land Before Time XII: The Great Day of the Flyers

The Great Valley turns barren and herds of dinosaurs have to find another place to inhabit. Cera, Littlefoot and Petrie, all kids, leave to find food and get stranded on a lush unknown island.

Littlefoot learns a series of important lessons following an incident that nearly costs his grandmother her life. Soon afterwards, three dinosaurs arrive claiming they have lost their way.

When the water supply to the Great Valley is blocked, Littlefoot and his friends must cooperate with a group of bullies to find the reason the cause.

Littlefoot's grandfather narrates the story about the Lone Dinosaur that killed a Sharptooth. A giant monolith formed after the fight and if it's destroyed, bad luck will loom over the valley.

When the dinosaur families get trapped in a valley by an ice storm, one family of "spike tail" dinosaurs volunteers to leave since they consume more food than the others. Meanwhile, the young dinos and a new adult dinosaur named Mr. Thicknose, head out to bring back their friend Spike, who has left his friends to be with members of his own species.
