The Land Before Time VI: The Secret of Saurus Rock

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.

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.

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.

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.
