We have a 3 head dropper from Poision props hanging where they see it before they enter a shack. Jigsaw is sitting in plain view in an electric chair as they approach the shack. Just before they get to the door way he drops the heads down in front of them... not on tp of them. They see the heads hanging but are so fixated on jigsaw they never suspect they will drop in front of them. Works great. One shack has poisons' Drop portrait with lunging zombie head. Of course that moves them away from tht wall...that thing is just sick after all flailing his head about ad screaming. Of course that moves them closer to othe wall where a drop panel and live actor/screamer is waitig to nail the peope at the back of the group. ront gets zombie drop..cowards in back get real actor from opposite side. Classic decoy them into thinking the surprise is sprung and momentarily let their guard down a little then hit them with live person.
