you set the Sol on the midle thing to get the stairs. hurry to the top and then hookshot it back to you from the top of the stairs before the hand gets it. if the hand does get it before you get outside. try your hardest to hookshot it out of his hand
You can also shoot it with arrows, takes 3 shots to immobilize it for a bit. It's enough time to hookshot the ball and run to the next room at least, and if not you just shoot it again.
