The Neptoona is a type of fish featured in Phantom Hourglass. It is a legendary fish, and there is only one of them in the entire ocean. It is incredibly large as well, measuring at 17 feet and 3 inches, and is the rarest and most sought after fish in the sea. They are very similar in appearance to Rusty Swordfish, and are found in swordfish shadows. Once caught, Neptoona cannot be caught again, and when shown to the Old Wayfarer, he will be overjoyed, calling Link a legendary romantic, and will also give him a Heart Container.
