if i remember correctly, the pumpkin is either in the Transylvania shop (not the tower). I think.
I just checked again - I'm running r43.1 so one behind the just released version - and there is currently zero shops in the Transylvania town and the devlog does not mention adding a store or the pumpkin set.
Maybe you were thinking of lust doll classic ?
Late reply, but if the shops and inn are locked, that means you still have things to do at the manor.
finish manor quest to unlock shops in Transylvania.
