What happens if

[HaleyRocks]

I place my Cursed Mannequins, inside a Big Shed instead of inside house? Are they still able to change location and change wallpapers, or not?

Since Sheds can also be decorated, i need to know in advance whether i run the risk of losing the wallpaper of my choice, or not.

I believe they have to be in a player house to do anything besides their normal function as a mannequin
