J.S.
I was also going to suggest familyfun.com.
We had a Halloween party last year & one of the snacks I did was a bowl of chex-mix. I bought a bag of gummy body parts (Walmart & Jewel had them). I took the body parts out of the plastic wrap & mixed them into the chex-mix. It's a simple idea, and the kids here enjoyed eating it.
Have fun!!
