Probably not! I had a little summer surf shop out that I have already demolished by now, but I don't think I'll end up paying any attention to potential Halloween decorations because it just doesn't do it for me (Halloween isn't even a thing where I live, so it'd be hard to get in the mood for something like that.)
Maybe there will be some really nice items added which I would use for general decorating. I'm not planning anything seasonal right now, at least.
in theory I would love to spookify my island (especially if the autumn update releases some fun new items!) but I've had no time or motivation to even look at my switch these last couple of weeks so it's up for debate... we'll see how it goes!
I'll probably end up decorating for Halloween. I dont think there will be a lot of Hallowern festivities this year, so Animal Crossing will be my spooky outlet.
