So this is for the Halloween update that has the locket as a purchasable item in the item shop.
What to do
Go to Val’s shop and buy the locket for $7
your first interaction is with Polly, your choice is to drug test the locket with the charm stat, or STAY HYDRATED with the smarts stat!
Polly is on a rampage so you have to help with The Coven (great) so you either find the kid who talks to ghosts with the charming stat, or use the Ouija board with the smarts stat.
You find Polly messing with the schools power in the basement (theres a joke here somewhere but not now) and you learn a bit more of her past, you ask her to talk about her father by using the bold stat, or tell her your not here to judge by using the charm stat.
Ask no one to prom!
