First, Go to the Fishing Hunt and inside. You will see a plate on the wall. This are total of four. Shot starting from left to right using your default gun. If you use a wall gun or gun that came from the box, This step will not work. If you got this correctly, you will hear a chime.
Second, Go to the back of the house where you will see a file of garbage. On that location, look for Samantha’s Doll. Then, press action key ( “F” for PC users ) and the doll will disappear.
Third, go out and on the bride you will hear and see that doll. Shot it with any gun you have and this doll will disappear and re-appear on different post. The doll will spawn six times. Once you got all of those six, the doll will disappear permanently.
