wich one is that again tell me and i will tell you how win

it is the one that has those weird electric tusk things on it

there isnt any answers to the question, you guys are just trying to find out what it is.

the thing that you fight in the sea

Ok ok, when you see the colossus, swim behind him and climb up his back. Note that if he
shoots electricity at you while you're swimming and above the water..it will do you harm.
So unless you need air..try staying below the water! When you climb up him and reach his
head, you'll see some things that resemble bone. If you hit them with your sword or arrow,
it will glow and the colossus will move in that direction..so you're basically steering
him. Try to get him close to one of the stone structures in the water, when you're close
enough..jump ontop of it. When you make it on there, hide behind the rock in the middle of
it, he'll be shooting at you! after he's had his fair share of missing you, he'll put his
feet ontop of the structure, in doing so..more of his body is out of the water. You'll see
his ONLY vital point on his chest/stomach area. Simply run from behind the rock and jump
on. Stab away!!
