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.

As the Great Day of the Flyers nears, the Great Valley’s flying youngsters are eager to participate in the annual exhibition to show off their skills. Everyone, that is, except free-spirited pterodactyl Petrie, whose individualism causes problems when it comes to staying in formation. Enter his dinosaur pals Littlefoot, Cera, Spike and Ducky, who encourage Petrie to embrace his uniqueness.

A bedtime story leads Littlefoot and his grandparents on a journey to a new land, where Littlefoot discovers someone who vanished before he was born: his father! Now Littlefoot must decide between two worlds. Will he leave to be with his friends in the Great Valley, or stay behind and start a new life with his father?

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 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. Littlefoot’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.

Legends claim that Saurus Rock keeps bad luck out of the Great Valley. Is it really true? Could the mysterious Longneck named Doe be the famous Lone Dinosaur, who can defeat a Sharptooth with his lasso-like tail? To find out, Littlefoot and company must cross theiGreat Valley and face a dangerous Sharptooth themselves!

This fourth sequel in the series finds “leaf gobblers” eating all the vegetation in Great Valley, driving Littlefoot, the young brontosaurus, and the other dinosaur inhabitants out. Arguments break out among the adults during migration, and Littlefoot and his friends decide to take matters in their own hands by crossing the “big water” to an unknown island. There they meet an old friend from The Land Before Time II–Chomper, the T-rex, who has to protect the gang from his own, carnivorous parents. Plenty of drama in this one, and as the series has been wont to do from the beginning, it shows adults as sometimes being less than perfect.

Beloved dinosaurs Littlefoot, Cera, Spike, Petrie and Ducky return in this story about the wonders of discovery that features new songs, including Donny Osmond’s “No One Has to Be Alone.”
