The Legend of Zelda: The Wind Waker -
Our next destination is one screen north over at Northern Fairy Island. Before going to the actual island, sail to the western portion of the square region where you will find a submarine. Defeat the bokoblins if you'd like for some joy pendants and then head inside. Drop down below and defeat all of the moblins. Once they are all defeated, climb back up and use the ropes to swing across to get to the the side of the room. It is very reminiscent of Niko's second mini-game on the Pirate Ship. Once you reach the other side, open the treasure chest to get Treasure Chart #22.
