Did anyone notice the tattoo on Stan's back on the episode The Legend of The Gobblewonker? If you translate the code on the stones from the Gravity Falls game Mystery Shack Mystery, which you can play on the Disney website, it will say 'Did you ever notice Stan's tattoo?' It's a compass. A map may be tattoed on his back or something, but this may be vital information and, if we can figure out what it is, it'll bring us one step closer to solving the mystery of Gravity Falls. Take it into consideration.
