99 nights in a forest.

5 kids have went missing from a mysterious deer. One is guarded by wolfs another by alpha wolfs and also another by bears. You were one of the five kids who got kidnapped by the mysterious walking deer with a long mouth and wide eyes that only came out in the shadows because it hates light. It kept you away in a cage underground in a forest guarded by polar bears. Fortunately the polar bears would also take care of you and inside the cage looked like a little nice kid room so that was good. Your backstory was that you were just sitting by a tree reading and got kidnapped. And alone in the underground cage. There could be a possibility though that if anyone were brave enough they could come out and save you, though they would have to kill the polar bears in order to get the key.
