Ice age

Back when the Earth was being overrun by glaciers, and animals were scurrying to save themselves from the upcoming Ice Age, a sloth named Brooke, a woolly mammoth named Ellie, and a saber-toothed tiger named Shira are forced to become unlikely heroes. The three reluctantly come together when they have to return a human child to its father while braving the deadly elements of the impending Ice Age.

This is a remake of the first Ice Age but instead of Sid, Manny and Diego as the main characters I've decided to use their mates with Sid, Manny and Diego's personality instead. I don't know if this have been done before but I thought it was a good idea.
