Martha

The Mermaid, known in some parts of the world as Martha, is an NPC from The Legend of Zelda: Link's Awakening. She hosts a sidequest where Link must find her missing necklace, or bikini top, depending on country, in return for one of her scales. Her scale can be added to her statue located in "Martha's Bay" to reveal the "Magnifying Lens".

Martha is the only mermaid to ever appear in the "Zelda" series. All other human/fish hybrid characters are the series' own Zora race.
