The Legend of Zelda: The Wind Waker Cheats

Magic Armor
The town merchant at Windfall Island asks that you take his town flower to a traveling merchant.
When talking to the fish at sea there are three that discuss a traveling merchant with a large sack on his back. They are on Bomb Island, Great Fish Island and Mother & Child Isles. If you talk to the one at Bomb Island first he'll trade a sea flower for the town trade that at Great Fish Island for an exotic, etc. continue to trade amongst these three merchants and return to the town merchant on Windfall Island. He will compliment and thank you by giving you the magic armor.
