Manny (Romano), Diego (Leary), and Syd (Leguizomo) have turned the heavily iced area into a camp for kids complete with ice slides and wading pools. One day a vulture Fast Tony (Jay Leno) warns everyone that the ice is melting and soon their valley will be flooded. So everyone has to migrate, fleeing to safer and higher ground. On the way, they meet 3 new friends: two opossums named Crash and Eddie (Sean Scott Williams and Josh Peck), and their sister named Ellie (Queen Latifah) who is a mammoth but doesn't know she's a mammoth. Collectively, they continue on their migration.
