Kenny moves back to South Park after eight years what happens when he sees his old friend group along with a old annyoing smoker that changed quite alot over the years?

(Based off the SBI AU of amazing artist @thechannelwithoutaname on tumblr {and YouTube!}, all credit to them for the ghost AU!) Tommy and his best friend Tubbo are stoked to learn that there's a place they can 'hide away' all summer. An old house from some part of Tommy's family that one of his aunts agreed to let them stay in. Problem is, there's a sort of 'local legend' going around, that say the house is haunted by the ghosts of the old residents, that died of somewhat questionable circumstances. A house fire, that no one seems to know how it was caused. Tommy and Tubbo aren't at all worried though. Because, ghosts aren't real!...right?
