Apparently it will help with Sally's tokens, but hard to say right now if it will be "worth it". I know I am going to get it, and I have plenty of gems for it, but on the event announcement livestream, they said there would be three promos during the event, so I am waiting for now to see if there will be a promo for the Mansion. Not sure what else the third promo could be for, other than maybe the Candy Shop? The Graveyard seems like it would be part of the storyline, so I wouldn't think that would be part of a promo. So far there have been two promos, correct? The parade float and Zero?
