How could i do a Twilight themed Sweet sixteen?

I don't think i am doing a big thing by inviting a bunch of people over but like what could i do? like Activity wise? I thought of like a bonfire La Push style but what else? like Decorating ideas and i think i will have everyone where something Twilight like a t-shirt or pin or just like Twilight colors (red and/or black). Maybe pin the fangs on Edward? I have music taken care of. OOO and what kinds of foods? And cake ideas are also welcome! Thanks a million you guys are life savers!
