Scare the people by throwing snow balls at them. Hold space to increase the power of your throw. Once you hit somebody, climb down and scare him some more! When you are done, climb back up to scare some more people. But be careful, the professor is sleeping in his tent on the other side of your cave. If he wakes up and takes your picture, you will be on the news, and reporters will be there to make your life miserable!
