You are a bear. One winter you were hibernating like usual, when a nasty storm came and woke u up. It shook stones loose in your den. It shook so many stones that your den collapsed around you. You are not a sad and homeless bear.
Looking out across the landscape, you see other burrows that you can use to shelter from the storm. You need a shelter or you will die!
You work up your sense of adventure and head off looking for a new life and a new home.
