Sid begins to wish for a family of his own, and so steals some dinosaur eggs which leads to Sid ending up in a strange underground world where his herd must rescue him, while dodging dinosaurs and facing danger left and right, and meeting up with a one-eyed weasel known as Buck who hunts dinosaurs intently. Diego is fed up with being treated like a house-cat and ponders the notion that he is becoming too laid-back. Manny and Ellie, having since become an item, are expecting a baby, which leaves Manny anxious to ensure that everything is perfect for when his baby arrives. So our three heroes, along with Ellie, Crash and Eddie, form the most unlikely family-in any 'Age'- as they embark on a mission across an ever-changing, increasingly dangerous landscape towards their salvation.After the events of 'Ice Age: The Meltdown', life begins to change for Manny and his friends: Scrat is still on the hunt to hold onto his beloved acorn, while finding a possible romance in a female sabre-toothed squirrel named Scratte. The only chance of survival lies at the other end of the valley. Manny, Sid and Diego quickly learn that the warming climate has one major drawback: A huge glacial dam holding off oceans of water is about to break, threatening the entire valley. Their only problems: They can't stand each other-and Ellie somehow thinks she's a possum! Ellie comes with some excess baggage in the form of her two possum 'brothers'- Crash and Eddie, a couple of daredevil pranksters and cocky, loud-mouthed troublemakers. That is, until he miraculously finds Ellie, the only female mammoth left in the world. Manny may be ready to start a family, but nobody has seen another mammoth for a long time Manny thinks he may be the last one. Manny the woolly mammoth, Sid the sloth, Diego the saber-toothed tiger, and the hapless prehistoric squirrel/rat known as Scrat are still together and enjoying the perks of their now melting world.
