Interesting fact about artist Hunt Slonem: he houses exotic birds in his studio and paints them often, as they are one of his signature subjects. Birds play a very important role in the Fall 2016 collection for Stacey, as well, and are depicted in a number of ways throughout.
bill does Not Fucking exist in this dimension bc theres nothing more boring than just recreating the whole show but with just the characters swapped
dippers special interests are ghost hunting + photography so i thought hey, why not base this au around the ghosts in gravity falls, a town which has attracted dipper due to the high amounts of psychokinetic energy in such a little area [ive explained it in >this post<]
the pines/stan twins are all chubby + trans
the mystery quartet are all trans and they care about each other a lot
all of the mystery quartet live in gravity falls and go to school together here, rick transferred in the 6th grade
dipper created the Entrance to the spirit realm aka the ghost portal. he treats it like a storage unit for ghosts. he gets accidentally turned half ghost and pushed into the portal. since hes part ghost hed be able to survive inside that dimension, he just has to stay a ghost for a very long time. mabel reactivates the portal and opens the hatch to bring dipper back, but in doing so she also risks releasing all of the ghosts AND the ghosts that were already in the spirit realm into the realm of the living [just like ghostbusters amirite,,,,]
