Zelda no Densetsu: Yume wo Miru Shima

Link returns to Hyrule after training overseas but is caught in a storm and stranded on Koholint Island. A man named Tarin and his daughter Marin, who looks like Princess Zelda, take him in. An owl informs Link that to leave the island, he must awaken the Wind Fish by collecting and playing eight Sirens' Instruments. The guardians of these instruments are known as the Nightmares of the Wind Fish. Once he gathers all eight, Link plays the Ballad of the Wind Fish and enters a large egg on the Tal Tal Mountains, where the Wind Fish is in slumber. Inside, he confronts the final Nightmare, which includes dark versions of previous enemies.
