The guide currently shows a member's version of the Meatcorn and Climbing hook puzzle. This puzzle also occurs in free worlds, with a slight difference...Instead of using the grapple to form a tightrope, there is a winch to pull out a bridge from the opposite ledge. Here is a picture of the completed room I came across. After making the grappling hook as in the puzzle shown in the guide, it is used to hook the ledge where the bridge appears, and then the winch in the middle of the room is used to pull the rope back, bringing the bridge with it.
