Carrie Has To Adapt
Once Carrie realized she wasn't in the Temperate zone, she started making some changes. The first change Carrie made was changing the color of her fur. Since she used her fur to blend in in the Grasslands, she has to change her fur to a white color to blend into the Arctic Tundra. The next change Carrie made was to grow thicker fur, to make sure she doesn't get too cold. The last change she made was to hibernate, so she could store up food for winter, and not have to try to hunt during winter. After she made all of those changes, she was able to live peacefully in her new environment.
