The more items from a set you have in a room, the higher your HHA score will be.
I think I have the clock and closet (and other balloon stuff) if you want them. What's the point of them, just to decorate a room with the balloon theme?
There's a balloon hat on the mannequin. I have so many spare furnitures I placed the rest in a museum exhibition room lol I still need chest, clock and closet.
