Three months after the events of the Ice Age: Continental Drift, Manny and his crew get ready for Easter. With Ellie struggles to make the decorations single-handedly, Manny and Diego try to watch some eagle fights between an eagle and different animals, Crash and Eddie try repeated unsuccessful attempts to prank Peaches (starting the first April Fools' Day), who wants to spend Easter with her friends, and Scrat, after he excavated in the underground from the Death Valley to the new herd's Valley and founded his acorn again, once again loses his acorn when it becomes a tree. In the meantime, Sid decides to look after eggs for the owners of them, much to the scorn of Manny and Diego.
