Tap the hourglass at the bottom of the screen, then draw the symbol in the area provided, it will not show up, but it will work.
You retrieve the bow and arrow whilst in the temple of courage. You use it to defeat the boss there.
no u use a boss key
the boss guarding the aquanine is Eox, Ancient Soldier
Depends on which game and your point of view. Personally, my favorite boss is Eox in Phantom Hourglass
The last boss is deep within the Temple of the Ocean King and is called Bellum
put a bomb on the cyclone and hit it
of course it's beatable. beat the final boss and you beat the game.
goron island in the southeastern sea chart.
Bomb the right cyclone and the bomb will hit the boss.
The order of the whole temple of courage is up, down, right, and left. So you must hit eyes in that order to get boss key for the temple.
Bellum is the final boss in the Legend of Zelda: Phantom Hourglass(A.K.A The Evil Phantom).
