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.
