when it gets dark, dressed as a vampire, go to your chosen location and put your soil on the ground with your fake body part sticking out.
then when someone passes nearby DONT do anything or make any noise JUST stare at them- this will truly freak them out. if they run you should run after them with your shovel- this will really scare them. this is best if you can get a group of you dressed as vampires and get another person to lead the victim to the location of your choice.
