Great Bay Temple
The Great Bay Temple is the third Dungeon in Majora's Mask. It makes well use of the Zora Mask. The main trick of this dungeon is to change the water flow and swim, using the Zora Mask, into different passages acquiring Small Key, Ice Arrow, and the Big Key. Link acquires the Ice Arrow after defeating Wart, a giant eyeball that can only be damaged when its eyelid is open. It is very similar to Arrghus from A Link to the Past, Queen Gohma from Ocarina of Time, and Deku Toad from Twilight Princess. The boss of the Great Bay Temple is Gyorg, a giant piranha swimming around a platform that Link stands on in the middle. Once defeated, Link seizes Gyorg's Remains and another Heart Container.
