The Western Fairy Island (A3 on the worldmap) is one of The Legend of Zelda: The Wind Waker's 49 distinct islands. On this island you'll find a fairy that'll upgrade your Fire and Ice Arrows, though in order for her to do it you'll have to bring your Skull Hammer with you so that you can destroy the blockade. Also found here is a Blue ChuChu next to the isle's palm tree, and a treasure chest near the island that contains a Silver Rupee (you'll need Treasure Chart #8 to get it). Far out in the ocean you'll find a sea platform. If you defeat the villains at the top of the platform you'll be rewarded with a negligible treasure.
