Zora Mask

You get this mask in Great Bay after playing the Song of Healing for Mikau. When transformed into a Zora, Link has the ability to walk underwater, doesn't have to come up for air, and can swim very fast. By pressing Z underwater, you use an electric shield attack that uses up some of your magic meter. You can also use a pair of boomerangs by holding B. The Zora's instrument is a guitar.
