Manny the woolly large, Sid the sIoth, Diego the sabér-toothed tiger, and the hapless prehistoric squirrel/rat identified as Scrat are usually still together and taking pleasure in the perks of their right now melting planet. Manny may become ready to start a family members, but no one has observed another mammoth for a lengthy period; Manny considers he may end up being the last one. That is, until he miraculously finds Ellie, the only female mammoth left in the planet.
Their only troubles: They can't stand each other-and Ellie in some way perceives she'h a possum! Ellie comes with some extra luggage in the form of her two possum 'brothers'- Crash and Eddie, a couple of daredevil prankstérs and cocky, Ioud-mouthed troublemakers. Mánny, Sid and Diégo rapidly learn that the heating climate offers one main disadvantage: A huge glacial dam holding off oceans of water is definitely about to split, threatening the entire area.
The just chance of success is situated at the other finish of the area. So our three heroes, along with Ellie, Accident and Eddie, form the nearly all unlikely.
