Biography
Martha inhabits Martha's Bay on Koholint Island. Schule Donavitch made a statue of her called "The Mourning Mermaid," which is placed near Martha's Bay, although it is not complete. She asks Link to retrieve her lost Necklace that was taken away by the waves. When Link returns her the Necklace, Martha rewards him with one of her Scales. Link can place the scale on The Mourning Mermaid statue to reveal a hidden passage where he can find the Magnifying Lens.

Trivia

 * In the Japanese, French, and German versions of the game, Link instead has to find her lost bikini top. This was most likely deemed too racy and was changed in the American version.
