Part 1 Get out your grappling hook , you'll use this heaps on this boss. One of the snakes heads will rear up and its about to shoot a fireball at you when you see it do this quickly grappling hook and connect two of the poles together on a diagonal angle because the fireball will bounce off the rope and go towards the snake head you're aiming at. Watch out for the other head because while you're waiting for the snake to throw a fireball at you the other head will be chomping at you trying to cut the rope line and eat you. After a few hits their heads will go under the water causing a huge wave to come towards you with blocks of ice in it. Jump onto one of the poles stay there for as long as you can then run towards the other side of the screen and jump onto that pole, dodging ice as you go.
Part 2
When they have their tongues poking out grab your grappling hook and hook one of their tongues to a pole, this will stun it so you can run over and hit it repeatedly with your sword. Continue this until another wave comes and do the same thing you did before. Then finish them off with a few more head-bonks. :P
if you mean the four legged dinosaur thing then here's how:
You can play as link or gongoron. So you need to start as gongoron adn wait for the beast to run and attack. before he hits you Dodge it and start to tap his side a lot so he tips over. when he is dazed on the ground, switch to link and take a bombchu and draw a path to the beasts' mouth so the bomb goes in it. Do that about two more times and he die. Gongoron leaves but the beast comme back to life. So you have to wait till he starts sucking in air and throw a bomb at him so he sucks in the bomb.then when he falls just start hitting him with your sword. continue this until he dies.
* When you play gongoron, link gets attacked occasionally by snakes so be careful!
Wait till the eye comes out, clawshot it and slash it. Do this until the boss starts swimming around. Avoid its inhaling attack, clawshot the spot on his back and slash it. Kepp on doing this until it dies.
Okay, so here is how to beat the Water Temple boss, Morpha.
Alright, so get your longshot out and target the nucleus when it is in one of the tentacles. The nucleus will then come to you which then you need to hit it with your sword, be quick, until it goes back into the water. If you stay in the opposite corner of Morpha or an adjacent corner, Morpha can't reach you. If it grabs you, it causes a lot of damage, about 2 hearts. Just keep repeating this process until Morpha is defeated.
(DETAIL- After you hit the nucleus a couple of times, Morpha will grow more tentacles. Watch out for them!)
Hope this helps! ;)
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
in legent of zelda,you has new sand from boss(if you win)and the phantom hourglass works ONLY on the temple of the ocean king.
put a bomb on the cyclone and hit it
goron island in the southeastern sea chart.
of course it's beatable. beat the final boss and you beat the game.
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.
