In Paper Mario: Sticker Star on 3DS, any time you find an object (scissors, baseball bat, radiator, etc) you can turn it into a special sticker. They are usually quite effective in battles, but several of them are required to progress through the game (e.g. the refrigerator cools down the volcano level).
However, I have found many objects and made stickers of them, but haven't found a use for them yet. I am very near the end of the game now so I was wondering, does every special sticker have a use somewhere in the game?
