Ice Age 2: The Meltdown (2006) ending / spoiler
All the animals make it to the arc at the other side of the valley before it floods. Manny, Diego, Sid, Crash, Eddie, and Ellie dont make it but the other side of the ice breaks open and the flood waters recede. A pack of mammoths come through the other side of the ice therefore proving that there are still mammoths left. Ellie and her brothers decide to stay with Manny, Diego, and Sid.
