I noticed that a lot of people can't find the top-right and bottom- left pieces of the photo "ready to go". Don't listen to other people, to get the pieces fly to spinon and use the sewer entrance closest to the asmodeus. Keep going down and right until you reach the room with the raised platforms that is drained of water. Pick up the green crate that is there and use it to get up onto the bottom left platform. If you go down the stairs you will find the two kittens that have the necessary pieces.
