Alternate costumes and DX camera:
Successfully complete the game and save at the end. Start another game with that saved game file. Aril will be wearing the skull shirt from the ending, Link will wear his pajamas from the beginning all the way through the game, and the DX camera that takes color pictures will be in your inventory.

Defeating the Dragon Roost Island Boss:
When the battle starts, use the grapple hook and grab on to the red tail that is hanging from the ceiling and swing across the Boss. It will cause a large boulder to drop on his head and stun him. Then, attack his eye with your sword to defeat him.

Trash in the ocean:
When you lower your hook from your sailboat near a glowing mark in the water, you might pick up trash, such as a boot, instead of a treasure chest.

Unlimited Lives:
Make sure you have at least two empty bottles. Fill one bottle with elixer soup. Set it to Y. Press START + Y together. Set an empty bottle to Y and press START. You should result with one full bottle of elixer and one half-full bottle of elixer.

unlimited health (and any other thing in a bottle):
Get a full bottle of elixer soup from your grandma and get at least one other empty bottle. set the bottle of elixer to any button Y. press Y+START at the exact same time (this may take a couple tries the first time). you should go to the start menu without the screen showing link drinking the elixer yet. set the empty bottle to Y, then press START.

You should automatically drink half a bottle of elixer soup. press START and you should have one full bottle of elixer soup, and one half-full bottle. the part below here you may or may not post i dont care this happens because when you drink something, the game doesn't say, "okay, take half of whats in this bottle away," it says, " okay, make this bottle half-full. it does this AFTER you drink it. in this case it says that to the empty bottle.

Hint:
Go to the tree on hide and go seek game. [the killer bees] do the roll attack on the tree were the old man is!the kid will fall off chase and get him and you will win the hide and seek game.
