Needle Rock Isle

Needle Rock Isle is an island in the Great Sea of The Wind Waker. It has a very tall pillar right in the middle, as well as a switch at the top of it that can be used to shut off the flames surrounding a chest in order to get the Heart Piece placed inside it. There is also a cave with its entrance frozen where, once inside, Link must light up six torches using the Fire Arrow to obtain 100 Rupees.

There are also three cannon ships in the surrounding waters. The golden ship contains a Triforce Chart which is retrieved by sinking the ship and using the Grappling Hook in the light-ring that appears. Like in other islands (such as the Crescent Moon Island), big jars on barrels can be found, although they sink when Link is too close to them.

Trivia

 * Despite the presence of a Triforce Chart near the island, the Fishman doesn't know (although he does suggest Link to destroy the warships that happen to have it).
 * The layout of the island's secret cave is the same as that of Diamond Steppe Island.
