Wait for a global Geemer to make the long trip along the map, or shoot a Super 20 to 30 seconds after entering the room to knock it off the ceiling and save a lot of time. Hold right against the bomb blocks, take damage from the Geemer, jump, aim-down, and shoot the Geemer shortly before landing. Samus should end up standing on the ground with the Geemer frozen on the wall with a 4-8 pixel gap between it and the ground (overlapping Samus' hitbox). Facing the bomb blocks and pressed against them, jump while holding down (but not crouched) and then hold forward (or forward and down) 5 frames later to break the aim-down pose. If successful, Samus will clip up through the ceiling. This can be attempted several times before the Geemer thaws.
