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

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 befriends with a mysterious, fun-loving dolphin-like creature named Mo, who is trapped in "new water" caused by heavy rain. The gang then goes on an adventure to the "big water" to bring Mo home.

On a day known to the dinosaurs as "Treasure Day", Bron becomes stuck in the Mysterious Beyond. This event urges the young Longneck Littlefoot to take his friends on a quest to the Fire Mountain to save his father. Along the way, they befriend a Flyer.

Littlefoot’s grandfather falls gravely ill, and the only hope for his recovery is the "Golden Night Flower" found in the treacherous Land of the Mists. Along with his loyal friends, Littlefoot embarks on a journey to retrieve the cure, joined by a shy newcomer named Ali, a long-necked dinosaur from a migrating herd. As they navigate the foggy, swamp-filled terrain, they are hunted by a pair of predators—a sharp-eyed bird and a massive crocodile—and must overcome their mistrust of the unfamiliar environment.
