Halloween -- Chinese Style?

As part of the immersion program, the school has decided to throw a Halloween Party, even though China does not recognize Halloween.  We had to come up with a list of ideas/activities and what we'd need for the party next week. As we brainstormed last night we discussed making them eat yucky food like brains and worms. Then it occured to us: The people already eat pig brains and chicken feet. They eat duck head and the eyeballs of fish. Their spaghetti already looks (and tastes) likes slimy worms and every meat is identifiable as an animal. How are we supposed to scare them with food?

Needless to say, there will be no "gross" food at this party. Or should I say, the only food there will be scaring us more than them.
