The Three-Eye Reef gets its name from the way it looks from above—inside the reef’s rocky walls are three circular, eyelike pillars. After you rescue Aryll from the Forsaken Fortress, enemy Warships and wall-mounted cannons appear here.
Treasure Chart #32
Bomb all the Warships and wall-mounted cannons to reveal a chest on the reef’s southernmost eye. Go to the narrow opening in the wall and walk up the slope and across the top of the wall to its highest point. If needed, play the “Wind’s Requiem” to direct the wind and use the Deku Leaf to float to the chest, which contains Treasure Chart #32.
Piece of Heart #33 (via Treasure Chart #38)
Find and open Treasure Chart #38 (at Windfall Island [D2]) to pull a chest from the Great Sea near the Three-Eye Reef. The chest contains Piece of Heart #33.
