Every moonfall will clip Samus 1 tile into the ground and Grapple must be used to return to a standing position.
A frozen enemy will need to be repositioned to a lower height at the point when Samus begins clipping into the floor with every moonfall.
The final clip may involve clipping into a floor, and from there moonfall clipping again to sink through a total of up to 4 solid tiles.
After 145 additional moonfalls, Samus' stored vertical speed is $FFD6.FC00, while after 146, it is $FFD6.E000.
