Hobbies And Interests
Infinite Health
Collect two bottles and a telescope. At Grandma's, fill one bottle with elixir and set it to elixir Y. Press "Start" and "Y", then place an empty bottle at Y. Select the full bottle of elixir again, and set it at "Y", and press "Y" and "Start." Select the telescope on "Y." When the elixir is consumed, a whole bottle will remain.
Alternate Music and Costumes
Enter the name "Zelda" as the player name to unlock alternate background music. To unlock alternate costumes, finish the game and start a new game with the finished game file. This unlocks Link in his pajamas and Ayril in the skull shirt.
Rupees
On the temple island near Outset Island, do random spinning attacks on the beach. Rupees come out of the sand. On Dragon Roost Island, go down the hole under the big rock at the Wind Shrine. Defeat the enemies and gain 50 rupees, then open the jars, which also contain rupees. Leave the room and come back to find the jars full again.
Magic Refill
On Forest Haven Island, find a flower that jumps the player into the air. Let the flower throw the player, without moving in any direction, several times. This will refill Link's magic.
