The plan nearly fails when the Sharptooth begins attacking the boulder while the group attempts to push it onto him. However, Cera, finally having a big change of heart, reunites with the group and headbutts the boulder, causing the Sharptooth to fall into the water below, the boulder crashing into him in the process. The Sharptooth momentarily takes Petrie down with him, seemingly to his death, but Petrie later emerges unharmed. Littlefoot, alone, follows a cloud resembling his mother, which guides him to the Great Valley. He is then joined by the others. Upon arrival, the five are reunited with their families: Petrie impresses his family with his newfound flight; Ducky introduces Spike to her family, who adopt him; Cera reunites with her father; and Littlefoot finds his grandparents. The group then rejoins at the top of a hill and embrace each other in a hug.
