"Hi, I'm Dipper. and the girl who's In a ball next to me is Mabel. We're stuck in this smelly dark closet of Stan's. you asking why, aren't you? well, were in the middle of a gravity falls zombie apocalypse.
Well, here's what happened. our arch enemy Gideon escaped jail last week. he hates us so much, but that's not the point. wait yea it is! ok, never mind, so he decided to break into the shack and steal the three books! he decided he wanted to kill us, so he summoned zombies. like, now isn't the best time Gideon! like, seriously? Mabel will never go out with you! and it was almost time for our 13th birthday! seriously? alright, so now Stan's outside waiting to kill any zombies that try to harm us, and Wendy, who's a lumberjack, (HOT!) is killing zombies with her chainsaw. well, back to the present!"
