A series of computer-animated films centering on a group of mammals surviving the Paleolithic ice age. The series features the voices of Ray Romano, John Leguizamo, Denis Leary and Chris Wedge.
With the impending ice age almost upon them, a mismatched trio of prehistoric critters – Manny the woolly mammoth, Diego the saber-toothed tiger and Sid the giant sloth – find an orphaned infant and decide to return it to its human parents. Along the way, the unlikely allies become friends but, when enemies attack, their quest takes on far nobler aims.
Manny, Sid, and Diego are currently living in a large valley surrounded by an enormously high ice wall on all sides. However, the trio discovers that the ice wall is actually a dam that is barely holding a massive body of water that could flood the valley to nearly a mile underwater. A vulture tells them that there is a boat at the other end of the valley that may save them all, but they only have three days to reach it or die. Manny is also having trouble fearing the fact that he may be the last mammoth left.
Times are changing for Manny the moody mammoth, Sid the motor mouthed sloth and Diego the crafty saber-toothed tiger. Life heats up for our heroes when they meet some new and none-too-friendly neighbors – the mighty dinosaurs.
While Scrat inadvertently causes the break up of Pangaea, Manny and Ellie are forced to deal with the trials and tribulations of their teenage daughter Peaches, who has trouble fitting in with her peers. Ellie tries to support her daughter, but Manny becomes exceedingly overprotective. Meanwhile, Sid's family returns, but only long enough to drop off the elderly Granny before abandoning them both. Shortly after, a sudden continental break-up separates Manny from The Herd. Trapped on a moving chunk of ice with Sid, Granny, and Diego, Manny has no choice but to ride out the current. Meanwhile, a giant land shift encroaches on Ellie, Peaches, and those remaining on land, causing them to make their way towards a land bridge.
When Scrat's acorn sends an asteroid to Earth, the Herd must find a way to stop the asteroid from hitting Earth with the help of a returning friend.
The fearless one-eyed weasel Buck teams up mischievous possum brothers Crash & Eddie as they head off on a new adventure into Buck's home: The Dinosaur World.
