Manny, Sid, and Diego discover that the ice age is coming to an end, and join everybody for a journey to higher ground. On the trip, they discover that Manny, in fact, is not the last of the woolly mammoths.

It’s a jungle out there for Blu, Jewel, and their three kids after they’re hurtled from Rio de Janeiro to the wilds of the Amazon. As Blu tries to fit in, he goes beak-to-beak with the vengeful Nigel and meets his father-in-law.

The story revolves around sub-zero heroes: a woolly mammoth, a saber-toothed tiger, a sloth and a prehistoric combination of a squirrel and rat, known as Scrat.
