Swing counter-clockwise around the floating Grapple blocks on the right side of the room, and release when Samus has high speed and is as far left 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 without bouncing. Hold left to roll over to the door. If successful, Samus will continue to gain fall speed, and will clip through the door soon after reaching it.

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.
