Some animals hibernate to stay warm and save energy when it gets really cold outside.

Imagine you have a big pile of blankets, and you wrap yourself in them so you don’t get chilly. That’s kind of what some animals do, they find a cozy spot, like a den or a burrow, and curl up to sleep through the winter.
