Acording to one websight I was looking at there are already some Halloween themed items in the data files. A carved turnip and some other stuff I didn't pay attention to becasue I was rolling my eyes.

it's just my opinion but I think adding seasonal themed items is fine when you don't have a huge backlog of things to fix or add to your game is a bit anoying. I can't help but wonder what useful items and/or interesting content the devs could have added in the time that they spent on these,
