The Land Before Time II: The Great Valley Adventure (1994)

Plot
Littlefoot, Cera, Ducky, Petrie, and Spike live a carefree life 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 chastise them for their recklessness. The next night, the children have a secret meeting and decide to prove their bravery and maturity by venturing into the Mysterious Beyond, a location outside the Valley that is inhabited by Sharpteeth. Before they leave, they notice two egg stealers, Ozzy and Strut, stealing an egg from the nest of Ducky's mother. The children pursue the intruders into the Mysterious Beyond. An ensuing landslide damages the Great Wall that surrounds the Valley and protects it from the Sharpteeth, and the stolen egg rolls safely back to the nest, but the group do not notice this in the confusion.

In the Mysterious Beyond, the group 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 Ducky's nest, they decide to hatch it. However, it does not turn to be Ducky's egg. Realizing its mistake, the gang does not know it's from another nest (though it really is a Sharptooth egg; and therefore, it belongs to a Tyrannosaurus family). The egg eventually hatches, revealing a baby Sharptooth. It was a sharptooth egg all this time. Although Littlefoot's friends are frightened off, Littlefoot quickly realizes that the baby Sharptooth is not yet dangerous, and decides to raise the newly-christened "Chomper" as his parent. This task proves difficult as Chomper is not an herbivore, and Littlefoot has no experience raising a child. Ozzy and Strut appear to exact revenge on the group for foiling their earlier theft, but are driven away by Chomper's enlarged shadow, which they mistake for that of an adult Sharptooth. The rest of the gang meets Chomper and they accept him as part of the group until he hungrily bites Cera by instinct. The group's knee-jerk reaction causes Chomper to run off in tears. The others follow him to a smoking mountain, where Ozzy and Strut attempt once more to attack the children, but are stopped when the mountain's eruption sends them plummeting down a canyon. After the group escapes, they encounter two adult Sharpteeth, who have managed to enter the Valley through the opening in the Great Wall. 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 the events that resulted in the landslide. The adults set off to put together a plan to close the opening 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. Chomper roars at them, and they recognize him as their son and leave with him. Littlefoot is then kidnapped by Ozzy and Strut, who plan to throw him off the Great Wall. Chomper hears Littlefoot screaming and leads his parents to Littlefoot's location. Chomper's parents rescue Chomper from an attempted intervention, and inadvertently do the same thing for Littlefoot by chasing Ozzy and Strut back into the Mysterious Beyond. Littlefoot bids Chomper farewell as he follows his parents, and he returns to the Valley to assist the adults in sealing up the entrance between the Valley and the Mysterious Beyond. Following his experiences, Littlefoot tells his grandparents that being young is not so bad after all, but decides he still looks forward to growing up.

Songs and Soundtrack
The songs are written by The Roches. This was the film that introduced the musical element into the series and it has consistently remained ever since. This was also the first time Spike "sings"; his lips can be seen moving during "You're One of Us Now". Also, even though the film features an original score by Michael Tavera, it contains musical cues from James Horner's score of the original film. Tavera has been the main music composer for the sequels ever since.
