I'm stumped on our bday party.... need ideas to push my brain

JQuin10

It's on saturday, bbq with family & friends. So far I have made these cute little bags with candy inside, and little cupcake toppers. The theme is super heros and everyone is to come dressed as one or make one up. Not sure on any games... can't think of any other decorations to make it stand out. If you have any ideas to get my brain moving I'd appreciate it!
