The game allows the player to take control of Manny, Sid, Diego, Scrat, Scratte and Buck as you take on or run away from dangerous dinosaurs, roll an egg to safety, chase after your beloved acorn, and explore caves and jungles over 15 levels. However, some characters are just for tiny parts in the game, like Manny and Diego. The main character in the game is Buck. There are eight mini-games to play either single or with friends in multiplayer and get things from Fast Tony. In the multiplayer mode you can play as Mini-sloths and Baby Dinos. There are 3 different bosses in the game, which are Ankylosaurus, Chasmosaurus and Rudy.
The cutscenes between the levels show Sid and Diego telling Peaches a bedtime story with the walls showing what their talking about, similar to cavemen drawings.

Sid falls down once again and lands on a seesaw with a rock on it. The rock falls down and propels Sid and he crashes near Manny and Ellie.
