Big Octo

Big Octos are extremely large Octoroks that reside in the Great Sea. They are only found in The Legend of Zelda: The Wind Waker. When Link comes across one, a whirlpool will begin. Link must use the Hero's Bow to shoot all of the Big Octo's eyes. Once the monster has been killed, a Great Fairy will provide Link with an upgrade to his Quiver, Bomb Bag, or Wallet.
