Spectacle Island "Beware the night when the crescent moon faces up! That's all I can tell you, small fry."
Spectacle Island "East of there is Windfall Island. I tried to enter my best drawing in the auction there. But I got rejected at the door! Why is there a dress code at an auction?"
The island is where the Barrel Shoot mini-game is located. Link can play it by walking up to the cannon on top of the tower, where he will find Salvatore. Playing this game can result in obtaining a Piece of Heart for the first successful run, Treasure Chart #17 for the second win, and 100 Rupees for every success after that. This mini-game, however, can only be played during the day since Salvatore will be asleep during the night.
This island is also one of the recurring destinations of the Ghost Ship.
