Hide-and-Seek Wager

Grandpa, will I get in trouble for going out to sea?

But you can't stop me! This village is too small for me.

One day, I'll sail my own ship and roam the world like Father once did.

Let's make a wager. I've left some of my treasured items along my route, so follow the trail and come find me!
If you do, I promise I'll behave from now on.

But if you can't find me, no more nagging. Deal?

P.S. I took that cherished key of yours. I'll need it to open the chest, right?
