Wait for the pirates to move as far right as possible in order to kill them all with a single Power Bomb. Jump over Baby Kraid by pausing and holding jump and forward just before the pause fully triggers, then remove Spring Ball. After it starts moving to the left, move in to where it was, then Crystal Flash so that it will walk back into Samus and trigger reserves.
