Hero Shrew

The changes that would happen if the habitat of my animal (Hero shrew) got colder, it basically starts to hibernate in a hole made out of wood and makes a nest where in fact is warm. And in the hole for the (Hero shrew) has a bunch of food it has been collecting so it has enough food to eat And that's basically it. My animal would change by growing more fur and its fur getting darker, basically going from gray to grayer and growing a little bit more than usual. And this is basically all for today.
