Shoot the Red Bird at the uppermost TNT Crate, but don't hit the small Stone rock next to it. If done correctly, a chain reaction should occur, killing all pigs except for the Corporal Pig. Shoot the Black Bird at the large Stone boulder above the Corporal Pig, and explode just when in nears the boulder. The boulder should roll down, and knock over another stone block which falls on and kills the Corporal Pig. The final unused Black Bird awards the player with 10,000 extra points.
