Output: Shortly after the events of the first film, Littlefoot and his four friends are living happily in their new home in the Great Valley, under their families watchful eyes. One day, the gang attempts to get to the sheltering grass to play, but land in the sinking sand surrounding it. The adults rescue them and subsequently chastise them for crossing the sinking sand. During the next night, the children have a secret meeting and decide that they need to prove they are mature by running away for a while into the Mysterious Beyond, a location just outside the Valley. Before they leave, they notice two egg stealers Struthiomimus named Ozzy and Strut, who have recently moved to the Valley, stealing an egg from the nest of Duckys mother. The children chase the egg stealers into the Mysterious Beyond. During an ensuing landslide that leaves an opening in the Great Wall surrounding the Valley, the five are sent into the Mysterious Beyond, while the egg rolls safely back to the nest. In the Mysterious Beyond, the five discover another, larger egg and mistake it for the original. The gang transports the egg into the Valley, and despite finding the original egg back in Duckys nest, they decide to hatch it. The egg eventually hatches, revealing a baby Sharptooth. Littlefoots friends flee, while he quickly realizes that the baby Sharptooth is not yet dangerous. Littlefoot tries to raise the hatchling on leaves; although this fails, the hatchling, whom Littlefoot names Chomper, becomes content with a diet of insects. Littlefoot then hears his friends calling for help, as Ozzy and Strut are attacking them out of revenge for foiling their meal plans during the previous night. Chompers shadow frightens Ozzy and Strut away, as they mistake him for an adult Sharptooth. The rest of the gang meets Chomper and they accept him as part of the group until he bites Cera by instinct. Chomper is told that this is considered bad behavior in the Great Valley, and he runs off as a result. The others follow him to a volcano, where Ozzy and Strut attack the children again. Chomper once more comes to the rescue, biting Struts tail. The volcano then erupts, lava slowly oozing in the childrens path. Littlefoot pushes a tree over a canyon to make a bridge for him and the others to escape the lava. Ozzy falls into the canyon while attempting to cross, and Strut jumps in after him. Once across, the young group encounters two adult Sharpteeth, who have managed to enter the Valley through the opening in the Great Wall, on the other side. They escape the Sharpteeth initially, but encounter them several more times. Eventually, the whole Great Valley population drives the Sharpteeth off, and the children make it back to their families, but Chomper feels left out and runs away again. The adults inquire as to how the Sharpteeth entered the Valley, prompting the children to explain their adventure the night before and the landslide that resulted. Realizing the landslide created an opening used by the Sharpteeth to gain access to the Valley, the adults set off to put together a plan to close the entrance for good, telling the children to stay behind. Littlefoot runs to the forest to find Chomper. After finding him, they are chased and cornered by the two Sharpteeth again. Chomper roars at them, and they recognize him as their son and leave with him. Littlefoot is then kidnapped by Ozzy and Strut, who survived the fall into the canyon and are planning to kill Littlefoot by throwing him off the Great Wall. Later, Chomper hears Littlefoot screaming as Ozzy and Strut attempt to carry out their plan. Chomper leads his parents to Littlefoots location and tries to intervene, but is unsuccessful. Strut grabs Chomper by the throat, and he and Ozzy are poised to kill him as well. However, Chompers parents rescue Chomper, and unknowingly do the same for Littlefoot. The Sharpteeth chase Ozzy and Strut into the Mysterious Beyond. After they say their final goodbyes, Chomper follows his parents while Littlefoot returns to the Valley, later assisting the adults in sealing up the entrance between the Valley and the Mysterious Beyond. Afterwards, Littlefoot tells his grandparents that being young is not so bad after all, but decides he still looks forward to growing up.
