Swing clock-wise around the two Grapple blocks at the top of the room, and release when Samus has high speed and is as far right as possible. Quickly morph, pause frame-perfectly so that the pause hits just as Samus would land, Equip or unequip Spring Ball in order to land on the door shell without bouncing. If successful, Samus will continue to gain fall speed while resting on the door shell, clipping through it after a few seconds.

If Spring Ball is unequipped after bouncing, it will cause the game to crash after landing from the bounce. To avoid this, do not unequip Spring Ball if the bouncing sound is heard before or while entering the pause menu. Alternatively, equip rather than unequip Spring Ball.
