Mystery Skulls Animated (Reader Included)

The Mystery Skulls Gang came across a haunted mansion. What will Vivi, Arthur, Mystery and Y/N do when there's a vengeful ghost, an obsessed plant and a possessed arm after them?

I've finally gone and done it. A reader included book. I may go onto xreader one day but today is not that day. All of this was written in a few hours, but i still don't know how exactly its gonna end (cuz the last episode isnt out lol) anyway continue if you want cringe!
(i couldnt be bothered to do my own cover cuz its just cringe anyway so cover isn't mine)
