History's greatest heroes return for the most outrageously funny and entertaining Ice Age adventure in two million years. When Scrat's acorn antics cause a cataclysmic crack-up, Manny (Ray Romano), Sid (John Leguizamo) and Diego (Denis Leary) go where no herd has gone before - on a high-seas quest aboard a floating iceberg. But a menagerie of misfit pirates are determined to shiver their timbers and capsize their journey home. Join a boat-load of lovable new characters (voiced by Jennifer Lopez, Aziz Ansari and Peter Dinklage) for original songs, spectacular animation and heartwarming family fun.
