how do you get through the snow tunnel.That eye moves fast and by the time i can hit him he already jumps on me
i agree, it is hard, but you just have to take good aim and hit him in the eye until he drops. when you do it a few times you go out of the tunnel. there isn't much more you can do but keep trying.
I'm quite sure that that you also have to fight a harder version of him much later in the game where sometimes his eye is closed and then you have to hit an explosive barrel when near it. My little brother claims (there is a high probability that it's true because I've never seen him lie) to have fought another one in a secret place and by killing it you get a heart container.
