Northern Triangle Island
Cyclos, the brother of the wind god Zephos (remember Dragon Roost Island?), may appear here in the form of a tornado. If at all possible, ignore him. Until a little while later, you will be unable to do ANYTHING about him.
When you get to the island, climb the ledges to reach the statue. Like before, it will ask Link to put the Pearl in its grasp, and, like before, Link will put the Din’s Pearl in its grasp. Nothing will happen. Sail to the final island in quadrant - Eastern Triangle Island.
Eastern Triangle Island
Here, you will find nothing but small updrafts - nothing to worry about, as they move in predictable patterns and merely rotate your boat if you DO get into one. As before, when the statue is approached, Link will be asked to put the Pearl into the statue’s grasp and Link will put Farore’s Pearl in its grasp. This time, something DOES happen!
Suddenly, the statue begins to shine brightly. Needless to say, sudden light cannot be good, and Link knows this. He quickly jumps off the ledge, and the statue stops shining. His expression likely represents your thoughts - "Huh?". Link, like an idiot, goes to re-examine it, apparently forgetting that it seemingly was about to explode earlier.
As he approaches it, it explodes, sending him flying for the second time in the game (it’s a home run!). The game zooms out, revealing that a large triangle has been made. The triangle soon begins to emit its own light, creating the image of the Triforce.
A tower begins to rise from the center. As it does, Link (finally) lands - right on the side of it. (Probably hurt a lot more than before.) As Link falls into the water, the King of Red Lions - somehow - catches up to him. The tower begins to assume its full height as the King of Red Lions explains that this tower was used in ancient times as a test of courage.
You must pass through the trials here to prove to the gods that you are a hero and are worthy of possessing the power to defeat Ganondorf. After the King of Red Lions finishes speaking, save and sail through the entrance to enter the third dungeon of the game - the Tower of the Gods.
