You awaken one day to find that it is freezing inside your little den. You lift up your head from your paws and see that a thick layer of ice has settled over everything in your den, even on your tail!

As you shake the ice off of your tail, you stand up and, as always, you hit your head on the roof. But this time, small ice crystals fall from it and drop lightly on your nose.

When you look out of your den door, you see EVERYTHING is icy. "What do I do now?" you ask yourself. You sit back inside your tiny shelter. You see two things you can do, but don't know which to pick.
