The Wind Waker

On Windfall Island (D2), Zunari, the man who sold you the Sail, isn't doing so well with his business. He asks you to help him diverisify his stock, by going to 3 different islands, (Bomb Island (E6), Greatfish Isle (D2), and the Mother and Child Isles (B2). He starts off by giving you the Town Flower, the first item in the trade. From here you can go to any of the merchants, and trade for different items, which will then be sent back to Zunari. This sidequest will give you two important things, a Piece of Heart, and the Magic Armor. The fastest way to the get Piece of Heart is listed below:
  1. Grab the Town Flower from Zunari.
  2. Give the Town Flower to Greatfish Isle's Wandering Merchant for a Sea Flower.
  3. Present the Sea Flower to Mother & Child Isles' Wandering Merchant for an Exotic Flower.
  4. Warp to Bomb Island to talk to the Wandering Merchant and obtain the Pinwheel.
  5. Warp to Greatfish Isle to trade the Pinwheel for a Sickle Moon Flag.
  6. Back to Mother & Child Isles and exchange the flag for the Fountain Idol.
  7. Return to Bomb Island and trade the Fountain Idol for a Big Sale Flag.
