Seems like a gd tactic ill try it next time
to save the last visitor, close the door, then take the toilet paper, put in the toilet and flush, turn the bathtub water on. Then it slips, open the cabinet under the sink, plug it in and put it in the water. then keep clicking the gun until the visitor is dead.
