Littlefoot, a young …
Littlefoot, a young Apatosaurus living in the verdant Great Valley, is awaiting the arrival of his father Bron, who returns once a year to lead his heard. However, he learns that his father has become stranded in the wilderness when the "fire mountain" erupted, and leaves on a journey with his friends Cera, Ducky, Petrie, and Spike, to find him. After a disagreement between Littlefoot and Cera on which path to take, Littlefoot decides to go ahead alone, where he meets a Pteranodon named Etta who knows his father. When the two become trapped in a cave, she sings a song to lead him on his way, and he is eventually re-united with his friends as they continue their journey together with Etta into the harsh landscape. Eventually, the elder dinosaurs learn about their children's trek, and decide to go after them with two younger ones - Chomper and Ruby.
