So, I just wanted to share this thing I did, I got all the old Halloween accessories by doing this.
~When you go to autumn town, go to the apple bobbing area.
~When your character starts bobbing for apples, wait til' it's done.
~DON'T MOVE from there.
~And then do the running man dance.
~Then you can go AFK apple bobbing.
Just check in every once in a while to see if you've moved slightly.
It worked best for me when I wasn't wearing any heels, they kinda make you move.
Hope this helps anyone. :3
