Inside is ........A KEY!
What does it open? Hmmm, you look around and find an
old wooden chest. You try the key in the rusty lock and
it turns a bit.
It's stuck. It won't move at all.
Maybe you should look around a bit more, there might be
something to make the key move.
You open the freezer. You don't think Dave is really
in there but you might find some treasure.
