Reinvigorated by the advice, Patchi escapes and fights off the Pterodactyls, before catching up to the herd, only to find them confronted by Gorgon and his pack again. As Gorgon easily overpowers and injures him in battle, a repentant Scowler orders Patchi to save himself and lead the herd to safety. However, Patchi leads them into fighting Gorgon and his pack to save Scowler instead of fleeing. The herd successfully drive off the Gorgosaurus pack while Patchi defeats Gorgon by dislocating his arm that had gotten caught in the hole of Patchi's frill before knocking out some of Gorgon's teeth with a headbutt, saving Scowler's life and avenging Bulldust's death. The brothers reconcile before Scowler concedes leadership of the herd to Patchi, who goes on to have Juniper as his mate and has a family with her, with Alex acting uncle. In the present day, moved by Alex's story, Ricky returns Gorgon's tooth to Zack and Jade, who had discovered Gorgon's skeleton buried in the ground. Cast In the film, the story of the dinosaurs is book-ended by live-action footage. Long, Leguizamo, Sircar, and Stone provide voiceovers for the computer-animated dinosaurs, while the book-end scenes star Urban as an uncle taking his nephew and niece, played by Rowe and Rice, to a dinosaur excavation site. For the role of Alex, Leguizamo said he sought to conceal his own accent and create a unique voice for Alex. He adopted a Spanish accent since parrots had a Latin American origin. He said, "What was most difficult was finding the right pitch, because Alex is a small bird, but he's also the story's narrator. So he also had to sound paternal and patriarchal." Leguizamo compared his accent to that of Ricardo Montalbán, a Mexican actor. Long said he was cast based on his voicing of the chipmunk Alvin in Alvin and the Chipmunks (2007) and its sequels.
