Workin' At My Fears(Requested Crossover and BoyxBoy)

After regaining Lewis, the Mystery Skulls head out to the small town of Gravity Falls. Why? To work at the mysterious kid's restaurant known as Freddy Fazbear's Pizza. Arthur doesn't know if he's scared or happy, he just knows that these are going to be long nights, for all of them.
Even more so with a stuttery genius and the king of asshats as co-workers.
Fuck.
(A few appearances of my favorite characters here and there. Expect to see Norman from ParaNorman, The Mystery Twins (duh), some anime characters, maybe Coraline and Wybie, but they most likely won't be very important. Just some characters to make you happy.)
