A buggy chest?

I know that my The Wind Waker disc has some problems. They aren't game breaking, by any means, but they're there. And they mostly manifest themselves in freezes.

You'll play for a lengthy amount of time, or have discovered a lot since your last save and suddenly Link is no longer responsive. Then it dawns on you like the sun over the Great Sea: The game's gone again.

Now, this hasn't happened yet on my current play through. But something stranger has.

In the south-eastern most part of the Great Sea, there's a submarine. It's surrounded by four platforms, one of which has a treasure chest just sitting on it.

Before going into the sub, I took out all of the bokoblins hanging about (after grappling away their Joy Necklaces), and then went to get said chest. A chest that seemed to have been there all along.

But it wouldn't open.

I'd done everything that you normally need to do in a Zelda game to get a chest to appear. But nothing. The chest would not be budged. So, I went through the sub, came back out and tried again - this time before knocking out any bokoblins. The chest opened and I found something minor enough to be almost immediately forgotten.

Because I'm playing on a pre-ordered copy, chances are this titchy treasure chest is a minor bug that was left in due to time constraints. But what if it wasn't?

To get treasure to appear in a room or area in a Zelda game, you need to solve a puzzle or beat all the baddies in the vicinity. This is how it's been since the beginning. But what if it was different? What if there was a chest that could be opened only if all of the enemies in the area were left alone? It's a possibility that could lead to some excellent puzzling.
