Can Voodoo dolls be moved?
From a strict reading of the rules, I would say no. Presumably, the dolls still do damage to you until they are destroyed. It wouldn't make much sense if you could remove them from their precarious positions and still take damage.

Then you must find the dolls in the room and destroy them.
Once you find a doll, you can automatically destroy it if it corresponds to you. You can find the location of any doll, but you can only safely destroy your own doll.
