Lighter

The Lighter is a Thing in Paper Mario: Sticker Star. It is the strongest of the fire-based Things and is found behind the Secret Door at Sandshifter Ruins. The Secret Door outline is found by going down the right-most sandfalls and entering the room at the bottom. Once collected, it remains in Mario's Album until it is turned into a sticker at a Sling-a-Thing station. Once it has been used as a sticker, it returns to its original position. It may also be purchased from the Shady Toad for 200 coins and sold as a sticker for 20 coins.

As a sticker, the Lighter takes up four squares in the Album. When it is used in battle, it rises partially from the bottom of the screen and ignites its flame. This produces fireballs that explode like fireworks as a joyous fanfare plays. When the fanfare ends, the Lighter lowers out of frame. Any enemies that are defeated turn into ash. The player can repeatedly press after the Lighter ignites to increase the damage dealt.

The Lighter can be placed into the Sticker Museum as #40, alongside other the fire-based and heat-based Things.
