Behind a statue, there is signs that will take you to a journey to get the heads of some mods. After you get those heads you can turn them in for items. But, the names of the heads in the villagers are different then the heads you get from the journey, which means that you can't get the item. Maybe someone changed it?
A specific case was hamrus1 being named ham and cheese or something like that. @MJB6 Please explain the situation with the hams head.
I had changed the heads in the shops to the costume heads because a lot of the signs to find the mod heads were broken
