Cat and mouse duo Tom and Jerry reluctantly work together to save a young girl from her evil aunt.

After an incident which nearly cost Littlefoot's grandmother her life, Littlefoot learns a series of lessons which his species call "Wisdoms". Meanwhile, a trio of dim-witted Beipiaosauruses named Loofah, Doofah and Foobie arrive in the Great Valley and behave in a strange manner towards Littlefoot and the gang. Littlefoot is determined that they learn the "Wisdoms" and the journey to the one place the trio have dreamed of, Berry Valley, begins.

Littlefoot and his pals set off in search of a "stone of cold fire" that fell from the night sky. Since he's the only one who has seen it though, nobody really believes him. Petrie's uncle Pterano offers support only because he thinks the stone has secret powers and wants it for himself but conceals this from the rest. The young dinos must figure out the truth, before Pterano gets the power.

Grandpa tells Littlefoot about their mythical hero called the Lone Dinosaur. Sarah gets two little lively cousins to take care of. Later, the kids accidentally chip the lucky Saurus Rock, and need to fix it before the bad luck hits.

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.

Petrie and his siblings get ready to fly for the Day of the Flyers, but Petrie is frustrated that he keeps flying out of formation. While practicing, he meets Guido, a Microraptor who does not know what he is, or where he belongs. With the help of Guido, Petrie learns how to be himself and stand out from the crowd.

The popular cartoon cat and mouse are thrown into a feature film. The story has the twosome trying to help an orphan girl who is being berated and exploited by a greedy guardian.
