Stealing
Your character can steal from shop by taking an item, and standing above the store keeper. As he looks towards of the top of the screen, use the door to leave the shop. Note: Your character will be branded a thief and may never return to the same shop. However, the game can be saved and reloaded if your character is killed by a store keeper, which allows the store to be re-entered without penalty.
You can steal items after getting your sword from the beach. Make the storekeeper look at the place where his goods are and walk left until you are above the door, Then, walk out. If this does not work the first time, try again. When you walk back into the store the storekeeper will kill you -- save beforehand and continue to do it again.
When you steal from the shop, get the storekeeper to look to the right, giving you more time to exit.
After you get Malon to follow you so she can wake up the walrus, go to the store. Pick up an item and just walk out. If you go back in, the shop owner will kill you. After you steal, Malon will call you "Thief" for the rest of the game.
Go into the village tool shop. Grab an item, then go above the man and follow the pattern: top, side, bottom and repeat until he looks at you very slowly. Then, when you are on the top, run out the door very fast.
Bonus seashells
Find exactly five secret seashells, then go to the Seashell Mansion. Enter, then walk right until finding the water flowing up a big pipe. Another bonus shell can be found by doing this with exactly ten seashells. Note: Return to the Seashell Mansion with twenty seashells to obtain a level two power sword. This sword can shoot when your character's life is full.
When you get twenty secret seashells, do not go to the Seashell Mansion. Instead, look for five more seashells so you will eventually have twenty five secret seashells. Once you have that number of seashells, go to the Seashell Mansion. Instead of a level two sword, you will get a powerful dagger. If you first go to the Seashell Mansion to get the level 2 sword and then look for the extra seashells, you will only find rupees in their place.
Free healing
Meet a fairy inside a cave and talk to it.
Getting the boomerang
Go to Toronbo Shores, the place where you got your sword, and look for a crack in the wall. Bomb the wall and enter the cave. If you do not have the magnifying glass, nothing will be there. If you do have it, a man will be there. He will trade a boomerang for whatever item is assigned to [B]. Give him your worst item (the shovel) to get the boomerang.
Unlimited money
Reach the Color Dungeon (accessible only with Game Boy Color), go up to the next room and then right into the next room. Go to the bottom wall and keep stabbing it with your sword. You will hear a hollow clank. Place a bomb there and you will be able to go into the room below. It is filled with five rupee pieces. To repeat this, just leave the dungeon and re-enter.
Wall check
Use the sword to stab at the walls. If a hollow clank is heard, a bomb may be used to open the wall.
Mad Batter locations
There are three places where the Mad Batter is located. The first location is in the Mysterious Forest. Go to the fairy in the Mysterious Forest and move left one screen. Lift the rock to reveal a secret stairway. Descend and sprinkle magic powder on the well. The second location is two screens to the right of the ghost's house. Blow up the bushes with explosive arrows. Jump the pit and enter, then move across the cave and swim through the water with your flippers. After leaving the water, move left and walk down the stairway. Again, sprinkle magic powder on the well. The final location is at Tal Tal Heights. Go to the Hen House and move left one screen. A lone bush will eventually appear after a couple of screens. Cut it to reveal another stairway. Go across the cave and get out. Keep moving left and up the mountain, then move left again. A lone rock should appear. Pick it up and walk down the stairways. Sprinkle magic powder again. Link should get 60 Arrows, 60 Bombs, and 40 Magic Powder.
Getting the master key in the second level
When you are in the room with a bat, a rabbit-like creature, and a arrow shooting skeleton, pick up one of the pots in the corner and move the blocks so you can throw a pot at the rabbit. Then, kill the bat hanging on the wall next to the rabbit followed by the skeleton. A chest should appear by the door.
