Right on left, you'll see like 3-4 pipes going out of the wall, stuck in floor. One of
them in the middle has the crank (you'll see it, pops out of the crank very obviously, to
the left). One thing tho....hurry up,as the doors to the cave opens and then is closing
itself on the other side. You can try as many times you want tho....
