I think the Halloween guy just follows you around to make noise for the girls to follow you easier
I think it is because why would all three of the girls slow down if you only shine one with the light?
I found a glitch with the new 0.7 Final update. if you use the max level flashlight and shine it on just one of the three monsters, they all get slowed down by 70% instead of just the one your shining slowing down.
