Pinatas are cool

When I was a kid, I went to a Halloween party and one of the games was guessing how many pieces of candy corn was a jar. The person who came the closest won a prize. I think the trick with a Halloween birthday party is balancing it all out--you don't want your brother's birthday to get overshadowed, but at the same time, you want to maintain the Halloween theme. I like the idea of a scavenger hunt. Maybe you could show a scary movie while they eat cake?
