Freeze the standing Pirate and one of the wall Pirates above it, to be able to moonfall between them. While moonfalling, charge a shot to kill the bottom Pirate, hold forward to change poses and clip past the Power Bomb blocks below.

To freeze the standing Pirate, it can help to 'doppler' it: stun the Pirate by firing an uncharged shot from a distance, then walk toward it while charging. Crouch while the standing Pirate is frozen, and when it thaws it will not see Samus. Allow it to walk as far left as possible, and freeze it again. Manipulate a wall Pirate using the fact that it climb upwards after jumping to the left and downward after jumping to the right. Frozen enemies thaw sooner in Norfair rooms, which makes this trick very precise. The clip will fail if Samus has either too little or too much fall speed. There is a 6-frame window to kill the bottom Pirate to fall with a correct amount of speed.
