It is required to avoid double hitting the Skultera with the Power Bomb, and to position the Crystal Flash so that the Skultera can hit Samus from above so it avoids the light orb. To do this, use the bottom-left Skultera, and move it off-camera at the far left end of its cycle. Go to the far right end of it's cycle and on the Crystal Flash on the sloped tile just below where it ends. Once the Skultera gets hit by the Power Bomb explosion, it will start moving, even while off-camera.

Dev note: There is no reason to do this at node 4, because the movement items required to get to 4 and then do anything useful with the flash suit would also enable Samus to get the flash suit here and then take it to node 4.
