  course). Go to sea map E3 to get60 bombs. Then go to sea map D6 to get
  99 bombs (the order don't really matter/same goes for the
  arrows).After that go to sea map A3 and G4.you need the skull hammer
  to get both arrow upgrades. Bombs for both bomb upgrades.

  If you want carry up to 5000 you half to go to sea map C1(you need
  bombs for this) you get 1000 rupees and then go to your home island on
  sea map B7(you need bombs and a Deku Leaf). First you go to the
  highest rock. Second you set the wind to the other side of the broken
  bridge. Third you fight a mothula( the gohma looking thing that shoots
  the thorny one eyed thing at you and has no wings). Before you pass to
  the log that you walk on there is a boulder. Blow it up and go into
  the whole. Then you encounter a fairy. Finally you have 5000 rupees 99
  bombs and arrows. Aren't you lucky!!
  

  

  

When you enter the boss room you have to walk forward a few feet and
  then it will show you a short clip of the boss coming out of the lava
  and then the battle starts.  What you have to do is pull out your
  grappling rope and swing it at the tail hanging from the ceiling. 
  when it latches on start pressing forward the backward until you are
  swinging very high.  then press A when reaching the climax of
  your swing to land on a platform(if you stay up there too long he will
  eventually start breathing fire on the platform which will burn and
  hurt).  then once you let go of the rope the ceiling will fall on
  top of the bosses head and it will show a clip of a layer of skin
  flying of the bosses body.  he will then push up and ram the ceiling
  back to where it was.  do this until his whole armor
  falls off, you don't need to swing any more now.  go down to
  ground level and when he hits his claws on the ground ready to breath
  fire what you do is run up and smack him with your sword(if you want to kill him faster
then target, pull sword out, and
  press A which does twice as much damage as a slash).  repeat this
  until he is dead.

  cannon) then go to two eyed reef ( two squares east from home island )
  and go to the patch of flying seaguls who are flying over the water.

  magic upgrade

  (deluxe picto box)

  Go to Forest haven and collect a forest firefly (the multicolored
  ones) then head to windfall island ,there go get the picto box from
  the jail. Show it to Lenzo ( the picto freak guy) He will say you have
  a nice picto box. leave then come back. he will give three picto box
  missions

  1. Go to the docks and wait for a guy in red overalls to slip a letter
  into the mailbox and take a picture .

  2.Go to the cafe and grab one of the bottles .stand far away (not to
  far) and through it at the guy at the table (daytime )

  Then as he's full of frieght ,take a picture.

  3. Stand near the school (or near it ) and aim for the girl in orange
  cloths. As time passes a guy will walk up to her and they will look at
  each other .Take a picture .

  Return to the picto shop and Lenzo will tell you that he has found a
  way to make picto's come in colour. Give him the firefly.

  HOW TO GET SONG OF PASSING

  Go in front of the guy dansing on the hill and take out your wind
  waker.

  

Stand on one of the seven-star islands and use a telescope to spot a
  group of seagulls(they usually hang out to the southwest).Sail over
  there and wait awhile for a giant octo to appear. You need a boomerang
  to do this. Lock on to the eyes and destroy them.When it goes down,
  use the grappling hook at the exact place it sank to find a piece of
  heart!
  

Aryll will have the purple "skull" dress on throughout the
  game. To get this simply complete the game.

  

To get 100 Rupies go to outset  Island. Go to your house. Crawl
  and go under the wood part nest to the ramp. Go inside the hole and
  there is the treasure chest with 100 rupies!

  

Once you found the picto box go back to the pictographer's shop and go
  upstairs to view his collection. After Lenzo finishes describing the
  photos on display leave the shop and go back to it moments later.
  Lenzo will then ask you to be his assistant. If you agre you'll be
  subjected to three tests.

  The pictographer wants to see your ability to properly compose a
  pictograph. After yo take each picto, return to the shop an show it to
  Lenzo to see if he approves it. If he does he will give you another
  challenge. The first challenge is to get a picture of a man putting a
  letter in a mailbox. To do this run down to the docks and wait for the
  guy in red coveralls to approach the mailbox. Take a picture of him
  just as he starts to place a letter into the mailbox. On of the most
  important lessons in pictography is patience, so stay out of sigh and
  wait for the right moment.

  The next challenge is to take a picture of a scared man. What you do
  is enter the cafe upstairs from where you bought the sail. Grab a jar
  and throw it at he head of the man sitting at the table. Quickly grab
  the picto box and tae full body snapshot of the man shaking. Be sure
  to stand far enough away so that his face and body can be seen
  straight on.

  The 3rd challenge is to get a picture of a man and a women making
  small talk. To do this head up the hill toward the school and ait by
  the small arch for the red-haired man to stop and talk wih the lady in
  the orange dress. Watch out for the school kids, they can get in the
  ay. Take a picture of them talking.

  Once you've done that Lenzo will reward you with a Joy Pendant. He has
  one final task in store for you, however. You must return from Forest
  Haven with one of the mysterious glowing fireflies trapped in a
  bottle. Once you give Lenzo the firefly, you'll receive the Deluxe
  Picto Box. 

  

After completing the game Link wil start his new adventure with the
  deluxe picto box (you can take color photographs instead of black and
  white).

  

To get unlimited knights crests. Get to the part when color returns to
  underwater hyrule castle. Kill the people which have swords. Do not
  kill the people with staffs. When you kill a person with a sword break
  the orb and pick up the knights crest that it drops. Then when you do
  that to all the guys with swords save and quit. Then return to your
  file. They will all reappear. Keep on doing this pattern until you
  have 10 knights crests kill everyone and leave. Go to orca and show
  him your knights crests. He will teach you the Hurricane slash. This
  isn't really a cheat but it is strange when you break a pot missis is
  carrying on Outset Island she will steal some rupees from you. Also in
  Windfall Island. Go to the bidding place at daytime so no one is
  gathered there. Break some vases. There are 8. For each vase you break
  you pay 10 rupees when you try to leave.
  

  

  

Finish the game one time

The Elixir Soup is similar to a plue potion, restoring HP and Magic,
  except you can use it twice and it also doubles your sword strength
  until you are hurt.

  To get it, return to Outset Island after completing the first dungeon
  (it may be second, I'm not sure-- the King of Red Lions will tell you
  to go there anyway). Your grandma will be sick, and the people will
  tell you to bring her a fairy from the Fountain on the island (this is
  easier if you still have one from the dungeon). Use the fairy when in
  front of your grandma and it will heal her.

  She gives you the soup and whenever you return, she'll give you more
  for free (it'd be a lot better if Outset weren't so far away from
  civilization!!)

  

  Hide and Seek Game on Winfall Island

  Talk to the teacher and find out that the children are misbehaving. Go
  talk to the leader and he will challenge you to a hide and seek game.
  Find all of the children in these areas. Run through the doorway
  nearest the tree, turn left, and the child behind the bush will run
  out. Catch him, then, roll into the top of the tree nearest the dock
  with the strange man walking near it. The 3rd child is behind the big
  stone the man is dancing in front of. The last child is behind the
  bomb shop. Simply sidle along the edge and run after him when you find
  him. They can all be found in any order. When you finish, go talk to
  the teacher for and the children again for a heart container.

  

  

When on dragon roost island go to the sign pointing up(If you are
  coming out of the boat,this to the right near the back wall)Use a pear
  to control seagulls to send one up. Make the seagull hit a bomb pear
  hanging above the sign pointing up. A treasure chest will fall near
  the sign. Open it and you will find 200 rupees

  

  What To Do With Skull Necklaces

  You can do 2 things.1: You can give 3 to the guy with the pigs on
  Windfall Island and he'll ask you if you want to "babysit"
  his pigs.Say yes and he'll ask you to find all 3 of his pigs within 2
  minuets.1 is by the ocean,another is by the 2 anoying litle girls,the
  last pig is by the jail.2: you can also go to the rich guys house on
  Windfall Island.(After you save the girls from the Forsaken
  Fortress!)Show him the necklaces and he'll buy each one for 10
  rupees.(5=50 rupees)
  

  

  

To get to the Nintendo Gallery you need to first climb to the second
  floor of the deku tree. Its the floor after the one where the tree
  spirit takes you. When you get there you will see someone standing
  next to a valt. Use your deku leaf to fly over there. When your next
  to the valt the person will ask you if you could fly over and hit a
  switch to open the valt. Put a pear on your head to control a seagul.
  The switch is somewhere on the side of the mountain. When the valt is
  open go inside. Talk to the guy behind the counter. He asks for a
  picture of a statue of some Nintendo character. I wont tell because
  I'm not sure were it is. But at least you know how to get in the
  Nintendo Gallery.
  

  

  

If you complete the game the text in the Hylian language will now be
  displayed in English.
  

  

  

When you get the delivery bag, you can start a trading event to get
  Magic Armor. First go to Windfall Island and talk to the guy with the
  parka during the day.Agree to help him get more items and he will give
  you a town flower. Then sail to Greatfish isle(section D2). You'll
  find a Goron with a huge pack talk to him a trade the town flower for
  a sea flower for about 20 rupees. Talk to him again and trade the sea
  flower for an Exotic flower for about 25 rupees. Then sail to Bomb
  Island(section E6) and find another Goron and trade the Exotic flower
  for a Sickle Moon flag for about 40 rupees. Then go back to Windfall
  and talk to parka guy. He will give you Magic Armor. It protects you
  from harm, but drains your magic quickly.(Note: Some of then prices I
  said might be wrong, so bring over 100 rupees just in case :)

  

  HIDDEN CAVE

  In Forest Haven go to the waterfall at the beggining of the
  level.Stand under the tree branch (or next to the waterfall).Use your
  Grabbling Hook to swing from the branch and into the waterfall on the
  right side(closest to the wall).You will end up inside.You can see
  torches along the wall and a few fire flies flying around. This is not
  required for the game but its a good place to relax.

  

  

When fighting two or more moblims L target one then wait till one
  behind the other then raise your shield then the moblim will attack
  the front moblim and it will kill it easier.

  

In the Deku Tree's Island you will have to save him from some blob
  creatures.  First, stand on the giant lilly-pad in front of the
  Deku Tree.  Little blob creatures will appear all over the Deku
  Tree's face.  To knock down the blobs, you have to do a rolling
  attack into the Deku Tree.  The blobs will fall. 

    Kill them all and you will see a cut-scene where you have to
  get up to the Deku Leaf on a branch.  Jump into a flower bud on
  the floor.  Try to face the next one (it is up higher). 
  When the flower spits you out  press UP all the way.  You
  will land on another one.  Continue doing this until you land on
  branch with one of the Deku Tree's children.  Aim your GRAPPLING
  HOOK at a branch and swing into the next flower bud.  Keep going
  higher up until you get the    DEKU LEAF.  Then
  you have to float with the DEKU LEAF to the next ledge so that you can
  exit to a new place.  Aim yourself at the ledge.  As soon as
  you jump off select the DEKU LEAF and hold the stick forwards. 
  If you timed it and did it right you will make it to the other ledge.

   

  TIP: WHEN YOU MAKE IT TO THE LEDGE, CUT THE GRASS TO REPLENISH YOUR
  MAGIC METER WITH MAGIC VIALS, BECAUSE YOU WILL NEED IT IN THE NEXT
  PLACE.

  

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).

  

When you first enter the boss room go to the middle and the boss will
  say something then it will come out, this guy is alike bongo-bongo
  from OOT but this time you have to shoot his hands 2 times and not
  once well you L-target his eyes and shoot 3 at each then he will come
  crashing to the floor then L-target his mouth and throw a bomb in it
  do it about 3 times to win
  

  
attacks-----what it does
  
  
SHOVE(hands)-----his hand pushs link off the
  stage

  GROUND POUND(hands)----he claps his hands then crashes them to the
  ground

  fire spit(head)----he spits out rapid fire balls at you *that's gona
  leave a mark*

  the reason i put this is because i did not think and tried shooting
  arrows at his mouth and boomeranging his mouth and slicing it and
  everything.
