First, get the Cabana Deed from the school teacher Then collect 40 Joy Pendants (on top of the 20 you gave to the teacher). You can steal Joy Pendants from Bokoblins, so be sure to visit the outlook platforms on the ocean. Visit the schoolhouse again and present her with them. If you have more than 40, she'll take those, too. As a reward, you will receive the Hero's Charm. You can equip this mask from the stats screen that shows your weapon, songs, and Triforce pieces. While it's equipped, you can see your enemies' hitpoints.
Get Hurricane Spin
Collect or steal Knight's Crests from the armored Darknut Knights. As soon as you have 10, go back to Outset Island and show them to Orca (the sword master). He will teach you the Hurricane Spin in return.
Easy Blue Potion
Although the potion shop in the island with the town makes blue potions using the teardrop items from the slime monsters, it needs 15 blue teardrops to make one blue potion. Instead, use the grappling hook on the monster plants on the island with the big tree to get the venus flytrap item. This item can be traded to the little plant shaman inside the giant tree's cave for blue potions at a better exchange rate (5 flytraps for 1 potion).
Easy Items
To get the purple backpack item that you normally get from an enemy without defeating it, simply target the enemy and use the grappling hook. If you do this with every monster you meet, you amass a gross amount of overstock.
Free Gold Potion
After clearing the first dungeon (and getting the grappling hook item), capture a fairy in a bottle (or buy a red potion if you're stupid) and head back to the island you started the game on (it is all the way on the bottom row of the overworld, the second square from the left). Locate the old woman then target and use the fairy/red potion bottle on her. Speak to her for a free gold potion. It behaves like a blue potion, but may be used twice. When the gold potion is used up, you can get a free refill by simply speaking to the old woman.
New Costumes and DX Camera
Beat the game to unlock a couple new costumes. Link will be dressed in pajamas throughout the adventure, and Aril will wear a skull shirt. You will also have instant access to the DX camera. To make this work, make sure you save at the end of the game, and start the game again with that save file.
Fairy Upgrades
There are eight different possible fairy encounters in Wind Waker -- and each leaves you with a very helpful upgrade.
There are six standard fairy wells. Upgrades are typically given in this order, independently of which fairy you visit at what point in the quest:
1. Bigger Wallet: holds 1,000 rupees
2. More Bombs: 60
3. More Arrows: 60
4. More Bombs: 99
5. More Arrows: 99
6. Bigger Wallet: holds 5000 rupees
Northern Fairy Island
Requirement: Bombs
Outset Island Fairy Well
Requirement: Deku Leaf, Bombs
Western Fairy Island
Requirement: Skull Hammer
Eastern Fairy Island
Requirement: Bombs
Southern Fairy Island
Requirement: Bombs
Thorned Fairy Island

Additionally, there are two special fairies:
Mother & Child Isle Fairy
Requirement: Balled of Gales
Simply warp to this island with the Ballad of Gales and you will receive the Fire and Ice Arrow upgrades (once you have the Hero Bow)
Big Octo Fairy
Requirement: Boomerang or Bombs
Look for the swarm of seagulls in the quadrant and shoot the Octo's eyes to free this fairy. She will double your magic meter.
Fun With Time
There is a clock-specific Easter Egg in the game. If your GameCube's internal clock is set to daytime, the background on the save game selection screen will show a blue daytime sky. If it's night, the screen will show be a starry sky backdrop instead. To change your clock setting, hold A while powering up your GameCube and select the Calendar function.
Messing With Tingle
Tingle is rather fond of his golden statues. Hit them with your sword while the GBA is connected and on and he will comment on your reckless behavior. Even better, take a statue and throw it into the sea. Doing any of this things will get Tingle so irrate that he will drop bombs on you and scream in very large fonts. Also, if you come back later and talk to Knuckle, he will tell you that someone dropped the statues into the sea. But don't worry -- the statues will be back where they were.
When Bacon Attacks
No, there are no chickens in this game. But that doesn't mean Wind Waker doesn't continue the "don't tease animals" theme. Try slashing at one of the little pigs on Windfall or Outset Island a few times, and you'll see what this all means?
Get easy knight's crests
Parry attack any kind of Darknut and get some armor. Keep using your grapple hook on him and get a knight's crest. Give ten to Orca, and he will teach you an ultimate move called the hurricane spin attack.
Get purple back-packs
Target enemies with your grappling hook to get a purple back-pack from them.
Change save-game background
If you change your GameCube's internal clock to daytime, the background at the save screen will show a blue sky. If you change it to night it will show a sky full of stars. Hold A then turn on your Cube to change the calendar setting.
Get elixir soup
To get elixir soup get a fairy and give it to your grandma after you beat the Forsaken Fortress the second time. The soup heals both health and magic plus doubles your attack damage until you get hurt.
Alternate Background Music
Enter "Zelda" as a name when you begin a new game to hear slightly different background music throughout the game.
100+ Rupees cheat
First, go looking around for three little pigs. Once you find them, pick them up and go up the hill left of your house. Throw the pigs in the pen and talk to the lady. She'll give you 20 Rupees for each pig! Next, go across the bridge and go the house to the right of the watchtower. Inside, crawl under the bed and through a hole. Inside is a treasure chest with 20 Rupees inside! Finally, go to the left of you house to the place with all the trees. Break them down and then get the 10 Rupee! The rest are just random 1 rupees.
100+ Rupees at the beginning of the game

Unlimited Elixir Soup
Required: one bottle. First go to outset island and fill your empty bottle with grandma's elixir soup. Here comes the tricky part drink the elixir soup but pause at the same time. You should be in your inventory. Now replace the bottle of elixir soup with any other item. Hit start and you should drink the elixir soup, but your bottle will still be full!
Air Glitch
To do this, you must have action replay. Then get the one that says jump (or mega jump but it really doesn't matter). Then when you come out through the start of dragon roost carven, jump and use the deku leaf quikly. Then keep holding R to keep flying up. When you are flying up make sure your on the side of valoo (the dragon). Then Link will be running on air!
Note: If you are over the dragon, just let go and you wil fall on air.
How to beat the big bird at Forsaken Fortress
You have to make it back to Forsaken Fortress with the Master Sword and the Skull Hammer. Once you start to fight the bird you have to run up to the top of the castle without falling down while he's attacking with his beak to the wooden floors. Once your at the top, the bird will fly in front of you. Pull out your hammer and attack his face. He will fly off and your allowed to enter the top of the castle. The door will close and the bird will come down. Dodge his attacks and once he attacks with his beak to the ground and is stuck, hit him with the Skull Hammer in the face. Repeat this 5 times until his mask breaks, revealing his face. He will still attack the same way, but you can now attack him with your Master Sword to finish him off. TIP! To kill him faster, after you get his mask off, instead of attack him with your Master Sword until he dies, attack him twice with your Master Sword and then hit him with your Skull Hammer twice. Repeat this until he is dead. You will recieve a Heart Container and allowed to Ganon's Ship.
