Islet of Steel

This island is one of the smallest in the game The Wind Waker, but is vitally important considering it holds a Triforce Chart inside it. It is located directly left of Stone Watcher Island or two squares north from Outset Island. The outside of the island is surrounded by a wall of steel with cannons embedded in it. Link must blow up all the cannons with Bombs along with defeating the armed ship guarding the entrance. In order to make the treasure chest holding the chart appear inside the island, Link must play the Wind's Requiem on his Wind Waker.
