Party Ideas?

What are some good ideas for a November birthday party? What could the theme be and what could we do? Think of us all being 11 and 12 year olds. I need it to be kinda cheap, and not so expensive. I just need ideas, I really don't need you planning it for me. So your answer doesn't have to be long, nor short, I really don't care, because best answer comes in all shapes and sizes....Anyway, thank you for answering! HAve a nice day! ♥
Sorry, but I really don't want my party to have anything to do with Thanksgiving. They're 2 seperate holidays.
