Use two snails to moonfall down through the pipe to the section below. The snails should be easy to align, with one on the floor and another on a ceiling 4 tiles higher. Slide off or shoot the lower snail after Samus has enough fall speed in order to avoid taking a snail hit. There is a small set of frames between these two, in which Samus will fall out of bounds. With Gravity, there is approximately a 5 second fall, with a 15 frame window. Suitless, there is approximately a 16 second fall, with almost a full second window - this is approximately 8 sets of bubbles out of Samus' arm. Clip down on the right side of the room without luring the snail underneath, or clip down in the center of the room with Spring Ball or Gravity and Space Jump and carefully cross the sand. Stand partially on the sand's edge to quickly overload PLMs, then go to the right and set up a pixel-precise high ceiling snail clip first try.

Dev note: It is possible to try multiple times with Gravity+Space+patience by moving the snail around the bottom of the room. It is also possible to use the gentle slopes in the middle of the room for a larger window ceiling clip, but the snails behave unusually on slopes and it ends up not really being easier.
