The Last Dragon
From the second fairy (the one inside the little castle) turn around and go back the way you came. to your left should be a metal door. Use super flame on it. There is ramp that goes up to a blue wizard and a whirlwind. Take the whirlwind up. jump up a few steps, go inside and you should find a suppercharge ramp. SuperCharge the two metal doors and there should be a dragon behind a wooden door.

After you find the second dragon and destroy all the doors go back up to the top of the supercharge ramp. Charge down and go out through the second door on the right.

Outside there is a circular ramp that goes around to the right. Ignore this ramp! Go left and while still holding square hit 'X' to jump at the very edge of the ground.

charge right through the door and up the ramp (same one before the whirlwind) jump again at the top of the ramp. When you get to the top of your jump you can let go of the square and hit 'X' to glide. You should end up on a grassy place with mushrooms and a whirlwind. Go up and inside to the left is the third dragon.

Up the Stairs
You need to get past them before they all come to life.

It is a matter of reflexes and practice. Stay to the right when you can. Try a few short charges here and there. I usually glide around the second to the last one (the last one that can hurt you) and then charge past the last one.

If they all come to life before you get past them go back to the Dragon. When you come back they will be dead again.
