Kill the Metroids while artificially morphed without any movement items. With just 5 Power Bombs, place one on the first platform to kill some Rinkas and to lure a second Metroid. Place a second in the same region, then drop down and quickly place a third on the second platform and fall to the third platform while the first two Metroids die. The remaining two Power Bombs can safely placed here to kill the final Metroid. Note that it is necessary to exit G-Mode before exiting the room in order for the Metroids to remain killed.
