[Haunty McSpooks]

I share everyone's concern about kids missing the connection to the movie, but I think most people who hadn't seen the movie would instincitvely recognize their creepiness.
And Spats nailed it:

I like the idea of a few being hung with other things, like mobiles made of bones and feathers, witch jars lit with candles, animal skins, kitchen utensils like giant ladles, cleavers and forks...
and bags, bags with something twitching inside.

Awesome ideas for presentation!
