Sid, the sloth, takes a school of children out on a camping trip from home, only to find that in typical Sid style, he is not a very good guide and the children he takes with him don't have a very good time.
Times are changing for moody mammoth Manny, motor mouthed sloth Sid and crafty saber-toothed tiger Diego in this third installment of the beloved computer-animated children's franchise. Life heats up for our heroes when they meet some new and none-too-friendly neighbors: the mighty dinosaurs.
Diego, Manny and Sid return in this sequel to the hit animated movie Ice Age. This time around, the deep freeze is over, and the ice-covered earth is starting to melt, which will destroy the trio's cherished valley. The impending disaster prompts them to reunite and warn all the other beasts about the desperate situation.
