When you have 10 Power Gems go to Spirit Island (South of Molida Island) and the spirit inside the cave will level up your spirit of courage and give you a fire sword which will do twice as much damage than normal.

There is no method to unlock Golden Ship parts, they appear randomly throughout the game like the normal ship parts except they're Golden and appear a lot less frequently. This has been done by Nintendo to encourage Online game with the WiFi trading feature.

When you have the Sun Key go to Molida Island and Romano's hut which is now a Shooting Range. When you score over 1700 points you will get the Bow Quiver Upgrade and if you get over 2000 points you will get the Heart Container.

Go to Maze Island in the Northwest Quadrant and complete Beginner and Normal modes. This will unlock Expert mode where one of the prizes is the Heart container.

Board the Traveler's ship in the Northwest Quadrant which is called 'The Prince of Red Lions' and fight the character on it. In the time given you have to hit him in exchange for treasure. If you then leave and return he will tell you to hit him 100 times and when you accomplish this task you will be rewarded with the Heart Container. If you carry on playing after that you will get more treasure and random ship parts.

Defeating Crayk, Bane of Courage:
At the beginning of your encounter with Crayak you will view the battle through his perspective. What you have to do is place Link in an area where Crayak can view him and wait for him to approach. Then shoot arrows at him and cracks will start appearing on his shell. Use your sword and attack him focusing on the damaged areas of his shell and eventually the shell will completely crack exposing his back and tail which has a blue area you need to strike with your sword. To get Crayak to stop moving when you battle him fire arrows at his face so he reverts to his battle stance. When he does this quickly get behind him and attack the tail. Keep doing this until the battle is won.

Defeating Cylock, Master of Wind:
To defeat this boss which is in the sky you have to send bombs up using the whirlwinds to bring it down. The easiest way to do this to send a bomb up a whirlwind which is in the same area as the creatures shadow. When a bomb hits this boss it will crash to the ground where you then attack it with your sword. Keep repeating this process until it is defeated but remember to roll to out of the way every time it plummets to the ground.

Defeating Diabolical Cubus Sisters:
Use your sword to deflect the Energy Ball your enemies throw at you and follow it's path back with your eyes. When the battle is nearly won and almost all your enemies have been defeated other projectiles will also be thrown at you. Ignore these and keep defelecting the Energy Ball back until the battle is won.

Defeating Blaaz, Master of Fire:
At the beginning of the battle this boss will split into three smaller enemies. Using the boomerang you have to connect them up again. Keep an eye on the top of the screen and the number of horns that the three sprites have when they make contact. The sequence when connecting them is 1 horn, 2 horns and then 3 horns. When the sprites have been connected and have formed one enemy again quickly attack it with your sword. Keep repeating this process until the boss is defeated.

When you are confronted with a group of Pirate ships destroy them and you will notice that the last ship you destroyed in the group will leave a red 'X' on the map. Go to this location to salvage treasure.
