Hey, if you want to know how to do this in a step-by-step, here it is. First you have to go around the arena until you find the spot on the wall where you stick your knife into those stones. Then you jump onto another one and across to the other side. Then you use a final stone and jump to the platform at the top of the arena. Ok, once you are there you walk out onto the plank (watch out because he swings his sword at you. You can jump to avoid being hit.) When you see the edges of the screen light up (go blurry, sort of), then you do the speed attack. You do this by shaking the nunchuk. Then you will fly though the air, and when you see the sword glow blue you have to shake the remote. This stabs him in the shoulder. Then you will run across his shoulders. While you is running, you have to be slowly tapping the C button to slow down time. (I like to have all my sands gone, so it doesn't go back too far). When you are slowing the time down, you will see the sword glow blue again and you shake the remote to stab him in the other shoulder. Then you will run up on his head. You have to be slowing down time and stab him in the eye when the sword glows blue. Then you got to get up on the other platform by getting on a plank sticking out from the wall and jumping to the other side. You get up on the highest platform and do the same thing you did with the first one. After he stabs him in the shoulder, the Boss grabs you and you have to be slowing down time and stab him in the hand. He then throws you in the air, and you land on his face. You have to be slowing down time and stab him in his other eye. He then cannot see, so you slash one of his legs and then the other. He will fall to the ground and you run up on his back. Slow down time and stab him in the back. While you are flying through the air, you have to stab him again. You will have to repeatedly slow down time and stab him every time the sword glows blue. Then he dies. FINALLY!!! Hope this is going to be helpful, because this is what I wanted to see when I was first trying to do it. Also, remember to be patient and keep the remote steady, because it is really sensitive.

I never slowed down time at all when beating this boss.. since it's all speed attacks you just have to react fast enough.
And if you miss the attack, you just rewind time a little and try it again

im still finding this bit hard lol. whenever i get onto his shoulder im never quick enough and he grabs me lol. thanks for the help though, im sure i will be able to do it soon
