Zora Link

Zora Link is the form Link takes after putting on the Zora Mask, and is specific to Majora's Mask.

Story
After Link finds Epona in Romani Ranch, he manages to gain access to the coast of Great Bay, only to find a dying Zora in the waters of the ocean. After bringing him back to the beach, he listens the last words of the Zora: He, Mikau the guitarist, was trying to retrieve the eggs of the vocalist of his band, Lulu; to do so, he had to enter the stronghold of Pirates' Fortress. However, the Gerudo soldiers within defeated him, and he was sent back to the sea, gravely injured. Because he can't accept death without helping Lulu first, he asks Link to at least calm his soul. Link then plays the Song of Healing and Mikau leaves to him his essence (materialized into the Zora Mask) before dying.

Link then explores the aforementioned fortress, as well as Pinnacle Rock, to retrieve the lost eggs, then goes to the Marine Research Laboratory to leave them in good hands, and finally the Great Bay Temple to purge the ocean from its current state. Because of these tasks, Link's Zora form becomes very important.

Abilities
The item is vital to the Great Bay Temple. Pressing B three times will make him lunge his right arm forward, then swing, attempting to hit something with the left fin, and end with him kicking up in the air, in a three-move combo. Holding the B button, he will put his hands together; by releasing it, his two arm-fins will break off and fly around like Boomerangs, flying in the air and eventually coming back to him. Zora Link can swim like a fish, which is much faster and more freely-controlled than any other incarnation of Link. Just pressing the A button will do it. While doing this, he can swim towards the surface, and he will leap in the air, much like a dolphin. He can also sink, and walk on the bottom of the body of water you are in.

Using the Dolphin Jump is key to defeating Gyorg. If he doesn't use that technique, he'll be chewed by the boss. Zora Link's boomerangs come in handy, and so does his next ability. While in the water, pressing the R button creates an electric aura around Zora Link; he can swim into enemies while doing this, and they take damage. Most die from this, but some like Gyorg just take damage. Pressing the R button on land will extend his right fin and make it into a shield. By holding both B and R, it's possible to create an electric aura on land, and moving with it by holding Z (like moving with a normal shield).

Instrument
His version of the Ocarina of Time is the Guitar of Waves. This is the instrument that Mikau played in life as a member of The Indigo-Go's band. This instrument is also required to give effect to the New Wave Bossa Nova melody, vital to help Lulu and to gain access to the Great Bay Temple.

Trivia

 * Dogs will come running up to Zora Link and make a whimpering sound, showing they like him.
 * The "putting on the mask" sequence will make Link's eyes big and black and give him a big mouth, much like a combination of the Deku Link's and Goron Link's transformation. but this scene can be avoided if Link wears the mask while in Deku or Goron form.
 * All Zora have a fin coming out of their heads. Zora Link has a green, pointed fin, much like Link's hat.
 * There are 3 well known glitches involving Zora Link. The first regards the Fierce Deity Mask. The second concerns a shed in Romani Ranch: First become a Goron and bounce up onto the shed. You will be able to jump into the Romani Racetrack by becoming a Zora. The final glitch can be attempted at Great Bay: Swim a little bit as Zora Link using the Dolphin Jump at the end of a swim move. In the middle of the jump, use a swim move. As long as you remain Zora, keep swimming and avoid above-water obstacles, you will be able to fly as a Zora. Medli, from a bird race called Rito, being Laruto's successor, could reference this glitch.
