The mother T-Rex, realizing Sid saved her babies, gently picks him up and… licks him. A truce is made. Sid says goodbye to the baby dinos, tears in his eyes: "तुम बड़े होकर अच्छे डायनासोर बनना, बेटों… और अपनी माँ की बात मानना।" Back on the surface, Ellie gives birth to a beautiful baby girl mammoth — Peaches (पीचेज़). Manny finally understands: You can’t control everything. Family isn’t about safety; it’s about being there for each other.
In Hindi dub, Buck says: "रूडी से बचना है तो मेरा हाथ पकड़ो। वरना… वो तुम्हारा नाश्ता बना देगा!"
One day, Sid stumbles upon three giant eggs buried under the ice. "Aha!" he thinks. "If I raise these babies, everyone will finally respect me!" He takes the eggs home, builds a nest, and starts singing lullabies in his broken Hindi: "सो जा रे प्यारे अंडे, तेरी माँ हूँ मैं सिड बेचारा…"
They slide down into the Lost World — and it’s stunning. Giant ferns, waterfalls, colorful flying reptiles, and dinosaurs of every size. But danger lurks everywhere: Carnotaurus, Pterosaurs, and a crazy, one-eyed Baryonyx named Rudy — a white-skinned giant with a scarred face and a bad attitude. Everyone fears Rudy.
Diego, inspired by Buck’s wild life, decides to stay in the Lost World a little longer — but Buck says no, the surface needs him too. So Diego returns, now at peace with being "soft."
Buck warns them: "No one goes near Rudy’s territory. No one."
Of course, they have to go near Rudy’s territory. They find Sid tied up in vines by the mother T-Rex, who is preparing to… well, eat him slowly. But then, Rudy attacks . The mother T-Rex fights Rudy to protect her babies — and Sid. Manny and Diego join the fight. Diego, remembering his warrior spirit, climbs onto Rudy’s back. Manny uses his tusks to push Rudy toward a lava fall.
