Shoot the scarecrows that appear from time to time in a target shooting level. After hitting its body eight times, its head will swell. Shoot its head for 1,000 points. If you shoot the heads of two scarecrows in the same level, an alternate third area with more gold targets will appear.
There is a level with birds carrying targets. You are told not to shoot the birds. When you shoot them, they will drop the target. If you shoot a falling target, you will get more points than if you did not shoot the bird.
