I would make it a gadgit/prank mansion,make all kinds of neat stuff like on myth buster.So when Tomie and prissy Katie poo came calling, O yea just put up all kinds of prankster stuff around like a door bell that was a loaded water cannon,then a trap door that would drop them into a water tank of yecky goo slime.Then when they climed out they had to clime thru a bunch of styrofoam pellets that stick too them. yea stuff like that and make a maze in there in the dark so they would wander around and Tomie would get all pissed and holler o.k. I get the joke o.k. can we get out now,then let this wind tunnel blow them around then ...well with 35 mill I could get really mind blowing so thanks for the fantasy.
Search through me,O God,and know my heart. Examine me,and know my disquieting thoughts,and see whether there is in me any painful way,And lead me in the way of time indefinite. Psalm 139:23,24
