About The Land Before Time II: The Great Valley Adventure
As the opening song of the film (Peaceful Valley) indicates, Littlefoot and company's arrival to the Great Valley is a relatively recent occurrence. The children are living happily in their new home, under their families' watchful eyes. When the gang tries to get to the sheltering grass to play, but land in the tar pit surrounding it, the grownups come and save them and chastise them for disobeying them, then lecture them that night. Cera then tells the others that they need to prove they are independent by running away for a while into the Mysterious Beyond, a location just outside the valley. Before they leave, they notice two egg nappers (Struthiomimuses) stealing an egg from Ducky's nest. They chase them into the Beyond, during which a landslide occurs. The egg rolls safely back to the nest, but the five are under the impression that it was destroyed in the landslide. This upsets Ducky until she notices what looks like the egg, only slightly larger.
