My son is a huge Ancient Greek themed movie or book guy, so after Percy Jackson came out he knew he had to have that as his next party. We decided on a movie night/sleep over in the backyard, and the boys loved it. The cake was mount Olympus, complete with Medusa, a two headed dragon & some gold coins. We watched Percy Jackson on a large screen we use for church & the projector in the backyard, the boys had movie theater food, (m & m's, popcorn, soda, other candy) & of course the cake. They also made S'mores on the fire pit after the movie was over. Not much in the way of decor, the movie took care of that. Enjoy!
