I think you kind of covered it - gypsy, maybe a seer/psychic, a seance area, not sure if you can score a live goat lol...........I would try to do something glow in the dark in terms of the firey pentagram that engulfed the victims.............for that matter, flies and gulp the poor kitty too!

Sounds like a fun theme - I also loved the flick. Good luck. I'm sure others will have more suggestions for you
