If we threw a Twilight vs Harry Potter party, what kind of snaks and games would tu bring?

Various harmless potions.
All red in color, served in white styrofoam cups with a straw.

Snacks: calabaza juice; Butterbeer; Firewhisky; Bertie Bott's Every Flavour Beans; Cauldron Cakes; calabaza Pasties; chocolate Frogs; etc.

Games: Exploding Snap; Gobstones; Wizard Chess

Also, any Weasley's Wizard Wheezes products. And the Weird Sisters would be good for music. I don't know how to entertain the Twilight fans (sorry).

Butterbeer and the cinnamon buns Edward made for Jacob, Seth, and Bella in Breaking Dawn haha xD
