last room. Here you will find a maple chest. The chest is to heavy to
carry, so push it back South until you come to the oak chest (note: you
must say "Push Maple Chest South"). Hmmmm, now, which chest to take? Let's
try the oak chest. Push that out West through the hole (carefully!

You don't want to cut your air supply!). Wait awhile, and the orange line
will appear. Get that, tie it to the oak chest, and tug on the line. The
chest will slowly make its way upward, while you return to the ship. Now,
push the maple chest south, past the sleeping squid, and south again into
the room with the ladder. Climb on the chest, and you'll be able to reach
the ladder and climb back up to the middle deck. From there, go North until
you reach the room with the cask in it.

Now, push the cask north with you, until you come back to the room with the
mast and the rope tied around it. Climb on the cask, then cut the rope with
the sword. Drop the sword (you can't leave with it), and then make your way
up and out. Once on the top deck, just keep going up until you're back on
the boat. The chest will be opened to display hundreds of gold coins.
Congratulations, you're now a very rich diver!
