My Dinner With a Loser

An orphaned brontosaurus named Littlefoot sets off in search of the legendary Great Valley. A land of lush vegetation where the dinosaurs can thrive and live in peace. Along the way he meets four other young dinosaurs, each one a different species, and they encounter several obstacles as they learn to work together in order to survive.

Littlefoot and his friends return in another adventure. But this time, they aren't the smallest dinosaurs in the valley anymore.

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 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.

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.
