I need some really good ideas on what to do for my birthday. I am having it at my house outside and about 40 people. I want to have a mardi Gras theme. I need help with what games and food ideas. I will be 16. Please help me!

my party is in a week and i dont know what im really doing yet. hang out, eat, watch movies, play twister, have a bon fire, and maybe you could make up some index cards with questions on them and give two to everyone and they can each ask anyone they want the question so that ppl get to know eachother better, it will be fun.
