Fairy Island

The Fairy Islands are heart-shaped landmarks on the Great Sea in, home to four different Great Fairies. While these islands may look alike, the method used to enter the Great Fairy Fountain is different for each, as is the equipment upgrade that Link recieves as a gift for visiting each Great Fairy.

Northern Fairy Island
Northern Fairy Island is a small, heart-shaped island in The Legend of Zelda: The Wind Waker located on quadrant A3 of the Great Sea. Unlike the other Fairy Islands, the entrance to the shell is not blocked by any obstacle. Link can enter to find a Great Fairy inside, who will upgrade the holding capacity of his Rupee Wallet to either 1000 Rupees or 5000 Rupees, depending whether or not he has received the wallet upgrade in Outset Island.

Western Fairy Island
Western Fairy Island is a small, heart-shaped island in The Legend of Zelda: The Wind Waker located on the Great Sea. The entrance to a shell on the island is blocked by a ring of fire, though by hitting a plunger with the Skull Hammer, the fire will recede, allowing Link to enter and receive a Quiver upgrade from the Great Fairy within.

Eastern Fairy Island
The Eastern Fairy Island is an island in The Wind Waker. The entrance to the fairy shell on the island is blocked by a giant boulder, so bombs are necessary to get inside. The Great Fairy that resides within will grant Link an upgrade to his Bomb Bag. Interestingly, despite its name, the island is actually in a portion of the Great Sea's northeastern region.

This island is home to a rare Blue ChuChu, and it's also where one of the Koroks' withered trees can be found.

Southern Fairy Island
Southern Fairy Island is a small, heart-shaped island in The Legend of Zelda: The Wind Waker located on the Great Sea. The entrance to a shell on the island is blocked, but by using a Fire Arrow or Bomb, Link can open the entrance and enter to receive an upgrade to his Bomb Bag. This is the only fairy island Link can warp directly to with the Ballad of Gales melody.

Once Link has bought the Treasure Chart from the expensive Beedle Shop, Link can retrieve a Piece of Heart from the bottom of the sea with the help of the Grappling Hook. Also, after every ship and wall-mounted cannon have been destroyed in every reef, a treasure chest will appear in this island containing Treasure Chart #40.

Thorned Fairy Island
Thorned Fairy Island is one of the islands of the Great Sea in The Wind Waker. The entrance to the fairy shell is blocked by vines that will only disappear by hitting the three switches with the Skull Hammer. Once inside, Link can receive a Quiver upgrade from the Great Fairy.

A Piece of Heart can be pulled from the bottom of the sea once Link has the proper Treasure Chart.
