Now even cooler in 3D! This new edition includes a 3D version of the film plus 4 pairs of 3D glasses!

Scrat is still trying to nab the ever-elusive nut (while, maybe, finding true love); Manny and Ellie await the birth of their mini-mammoth, Sid the sloth creates his own makeshift family by hijacking some dinosaur eggs; and Diego the saber-toothed tiger wonders if he's growing too "soft" hanging with his pals. On a mission to rescue the hapless Sid, the gang ventures into a mysterious underground world, where they have some close encounters with dinosaurs, battle flora fauna run amuck - and meet a relentless, one-eyed, dino-hunting weasel named Buck.
