Yo-ho-ho in the Ho-ho-hold
In a dusty corner of the hold, you find an old treasure chest! Maybe the pirates forgot to bury it! And it's unlocked! How exciting!
You slowly creeeeak open the lid, and... it's empty. Aw, man!
Oh wait, it's not entirely empty -- there's a key inside. Which turns out to be the key to this chest. You take it with you anyway, just on the off-chance it also happens to fit any other pirate treasure chests you might encounter.
