Kill the Metroids while artificially morphed with just Spring Ball to avoid them. A Metroid (or a Rinka) must be completely on screen while a Power Bomb explodes in order for it to lure the other Metroids. One strategy for this location is to wait for the Rinkas to fire twice, then place a Power Bomb in the hallway to the right and return to lure one. Jump over it twice and at the top of the second jump place a second Power Bomb; this one will explode when the other two Metroids arrive. Jumping high to the right can also help get them stuck in the top right corner while placing a Power Bomb. Note that it is necessary to exit G-Mode before exiting the room in order for the Metroids to remain killed.
