Join Littlefoot, Cera, Spike, Ducky, Petrie and shy newcomer Ali on one of their most exciting adventures yet! A herd of migrating Longnecks has important news of weather changes in the regions beyond the Great Valley. What was once dry land has become "The Land of Mists". Strange new creatures have begun to appear in these rainy marshes, while still others have moved into the high trees from which the Longnecks used to feed. Fortunately, the Great Valley is as beautiful as ever. There's no need to brave the wetlands - until Littlefoot's Grandpa becomes ill. His one hope is to eat the healing petals of a golden Night Flower that only grows...in the Land of Mists! Now it's up to Littlefoot and his prehistoric pals to explore the swamps, outwit sly new villains and find the Night Flowers in time to save Grandpa. Along the way, the kids will learn some loving lessons about teamwork, cooperation, and most important of all: that it's great to have friends of all kinds, in all shapes and sizes. Sparkling with delightful songs, dazzling animation and a heartwarming story, The Land Before Time IV: Journey Through the Mists celebrates the power of embracing the differences that make each of us truly special!
