The Wind Fish's Egg and ending
Prepare the final route after gathering the eight instruments. Contains story spoilers.
Original monochrome 1993 Game Boy release. The Color Dungeon and photographs from Link's Awakening DX (1998), and the Switch remake's extra collectibles and equipment layout, are outside these guides. Period official guide artwork is identified in captions.
Read the library before the egg
After completing all eight main dungeons, return to Mabe Village Library with the Magnifying Lens. Read Dark Secrets and Mysteries of Koholint to learn the directional sequence for the Wind Fish's Egg. Write down the sequence from your own file because it can vary. A route copied from another playthrough is not a dependable substitute for reading your game's clue.
Open the egg and follow your sequence
Go to the giant egg on Mt. Tamaranch with the eight Instruments of the Sirens. Play the Ballad of the Wind Fish using the Ocarina to open the entrance. Inside, drop into the maze and follow the directions you recorded. Enter with restored health and ammunition for the equipment you use; solving the maze leads into the final Nightmare battle instead of another ordinary dungeon.
Respond to the Nightmare's forms
The final opponent changes forms, asking for different responses: Magic Powder handles the first blob form, the sword returns Agahnim-like projectiles, and later phases use the sword or a charging attack. In the final DethI phase, jump its rotating arms and attack the open eye with arrows. Completing the original game without a recorded death adds an extra Marin scene after the credits.
Record the egg directions from the library in your own save file.
