School's Out!

There are four elementary schools in Hillstown: Redwood, Yellowton, Bluebird and Orangetree, all bordering one favorite playground with one favorite hill. After school, all the kids rush to the hill as soon as they can to claim it as their own, so they can play with their friends and not the losers from the other school. To claim it, they must stay on the hill and knock the kids from the other schools off. This is treacherous. This is war. This is KING OF THE HILL!
