Sneaking out ideas? 20 characters?

I have no idea what Beaver Island is but just stay there til 7 then pull pranks on people at walmart x) If you get bored or they kick you out after a while then go to the theaters and see a movie. You could dress up in a halloween costume or something like a vampire and scare the crap out of people. But be careful you never know what kind of people they are or if they'll have a heart attack haha so maybe not.
