That's one of the possibilities that I've been thinking of for her future levels, I don't know what will end up happening but I'm already thinking about it!
Anyway you implement it all I know is that it'll look amazing in the end. I loved getting jumped by Anney from the "Cafe" at the draining grounds that was a pleasant surprise.
Oh here's other idea that might be an interesting concept. Like Anney are you going to have different people from around town show up at the draining grounds when they either want to "burn off" some size or get huge. If I remember correctly you already did the Carpenter as well.
Speaking of the Carpenter is there going to be more done with her alongside the other folks at the Mall besides buying one to two items?
