Four-Eye Reef

In The Wind Waker, the Four-Eye Reef is a large square reef with four round reefs within it, resembling a six-sided die. Once Link defeats all the gun turrets, he will receive Treasure Chart #19. The Great Fairy Chart can also be retrieved here by using the Treasure Chart found in the Five-Eye Reef.

Fishman's hint on Four-Eye Reef: ''You've seen those weird rings of light that appear on the surface of the sea, haven't you, small fry? Did you know that some of those rings only appear at night? Didn't think so.''
