This crossbow will fire by itself without you having to press anything, and if you stop grabbing at any point after this, it will disappear. Grab onto one of these pairs to get yourself a crossbow. You'll come out by two big red buttons and several pairs of sticks with red hands on them. By the first box we just climbed will now be an open door head through this and ride the fan that's been turned on all the way to a new area.

Grab this and jump down to place it in the next slot. You'll see that they've formed a staircase, so climb up them to a ledge with another battery. Now step on the two yellow buttons nearby to move both boxes into place on the other side of the room. You'll see two ramps on the right go up one of them and place the box into the yellow square, then grab the other box here and place it in the square on the other ramp. Head back to grab the box and take it through to this new room. Push the box off the edge, then grab the battery and jump down with it to place it in its circular slot below. Now clamber up the stacks to the ledge at the top with another battery and yellow box. Lastly, press the green button again and push the smallest stack into the middle, then press the button once more and move the smallest stack into place behind the others. Head back and push the medium stack straight across to the tallest stack. Press the button again and push the stack back over to the wall by the door we just went through. Push the green button to move the lines on the ground, then push the tallest stack into the middle (make sure it's clean in the middle so it's lit green underneath). To the right here is a puzzle where we have to move the stacks into place. Follow the path onwards to enter a room with a giant fan and head out to the left. Once you've knocked down the pin at the end of the lane ( Bowling Lane 1/4), it will open the way ahead as indicated by a green arrow. The best timing for this seems to be when all the obstacles are on the right and about to move back over to the left. Pull the lever back and watch the lane ahead, and when you think the path will be clear for the ball, let go of the lever to push the ball. Grab one of the bowling balls to the left of it and carefully place it right in front of the lever behind the lane so it doesn't roll away, then jump up behind the lever. We land right by our first Bowling Lane there are four of these to complete for an achievement and this one must be completed to progress further into the level. Grab this and walk up the stairs to place it in its slot, then stand on the green circle on the platform and you'll shortly be launched over to another roof. As you drop into the level, you'll be right next to a yellow battery.
