Curling Stone

The Curling Stone is a Thing in Paper Mario: Sticker Star. It is the third strongest of the ball-based Things and is found at Ice Flow. It slides downs the first ice river indefinitely until Mario picks it up. 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 location. It can also be purchased from the Shady Toad for 300 coins and sold as a sticker for 20 coins.

As a sticker, the Curling Stone takes up 1.5×1.5 squares in the Album. When it is used in battle, the battlefield darkens as Mario forms a bowling stance. After he thrusts his arm out, the Curling Stone slides into any onscreen enemies. A graphic displaying the word "WINNER!" appears after the it collides with all the enemies. The player can press as Mario thrusts his arm to increase the damage dealt.

The Curling Stone can also be placed into the Sticker Museum as #30, alongside the other ball-based Things.

British English Sticker Museum description
"It seems increasingly possible that this boulder spontaneously grew a handle out of its top. The wonders of nature are endless...and really weird."
