Battle Spinner is used in battles to give Mario a chance to use more than one Sticker in the same turn. He must match two or three pictures in order to gain more attacks. If Mario is not feeling too lucky, he can actually pay fifteen coins (plus fifteen more to use it again and again), to automatically have two pictures lined up. This ability is very helpful for boss fights.
Super Battle Spinner
The Super Battle Spinner is an advanced version of the regular Battle Spinner. It is used by Mario in the very last fight with Bowser after Kersti gives up her life to turn herself into a Sticker. With the Super Battle Spinner, Mario can use a total of five Stickers per turn for the rest of the battle. Mario's attack power is also increased greatly while Bowser's defense as dropped.
