Moonfall onto the Homing Geemer walkway twice to clip all the way down into the ocean below. The Moonfall must be performed at the very edge of the slope so that Samus fully falls to the lower area. The first Moonfall will clip into the slope above the walkway, and the second Moonfall will clip all the way through. Pose changing can send Samus inside of the walkway, where the right door connects to the WS main entrance door, and the left door connects to the Moat door.
