Freeze an Atomic near the bottom of the stairs above the bomb block, so that it is barely off-camera when Samus drops down. Below, prepare a second Atomic to be frozen. As it approaches, jump up to cause the upper Atomic to come on-camera and descend. Take a hit from the lower Atomic, and freeze it about 1.5 tiles above the floor; use the i-frames to jump on top of the lower Atomic and freeze the upper Atomic while it is inside Samus' head. Immediately moonfall to the left. If successful, Samus will clip two tiles into the floor. Turn to the right, and perform a turnaround spin jump to the left to break the bomb block using Screw Attack. If Samus clips through the Atomics but does not clip into the floor, it means the bottom Atomic was frozen too low. If Samus clips only one tile into the floor, it means the bottom Atomic was frozen too high.
