What do you hit to get the bandits out of their hiding places in Wild west island?

You have to shoot stuff around them to hit them and then they will run out for like eight seconds...... examples.....( when you shoot the candle, it will light up the rope and then the person will come out and walk back and forth, also you could shoot the gun it will do something,i forgot,but it will get the person to come out, also you can shoot the bag of potatos to hit the person it they will come out.)
