Accomplished in one shot. Launched lazer bird to the "southern hemisphere" of the moon/planet where it breaks away from the gravitation field just under the bottom large space rock. Changed lazer Bird's direction to "north" after passing large space rock to deflect small space rock back "west" to hit pig and hit large rock towards pigs to the north. Large rock falls onto right planet; lava boulder falls to left planet and wipes out crystals. One remnant of lava rock after explosion makes it's way back to right planet to take care of remaining pigs and debris.
