NDS Zelda Phantom Hourglass Help!!!

Need Help on NDS Zelda Phantom Hourglass!!
I can complet Isle of Ember , I can`t get in castle of fire, i saw a box whit a key (i fink so) on a small isle but i dont know how to get there

Did you light all of the torches?

Lol If I remember right you have to light all the torches with the boomerang.

Uhhh....

Go into the fortune teller's house, and go down the stairs. Bash the enemies, then tap through the part where the fortune teller speaks to you.

Tap on the map to the right of the door, then tap on the following places:

1. On the small island to the very right of the main island.
2. To the top left of the island, you will see seperate isles. To the right of that; where a curved path ends.
3. the house below the fortune teller's.

After this, the fortune teller will open a gate for you, and you can go through it and you will be on your way to the fire temple.

If this is not where you are stuck, please explain in further depth where and how to are "stuck".

OK. right i have just got to the entrance to the temple of fire. But it asks to blow out flames or something?
How do i do that? i am assuming that i am missing a piece of equipment here or something??
:)

im guessing knowing the DS, blowing out the flames means blow into the mic.
