Kururin Ball is an attack part used in Mario & Luigi: Bowser's Inside Story.

When using this attack, Luigi hops on a giant ball, and Mario has to spike it ("A" button). After a while, it falls on enemies. While it's landing, the player has to control Luigi to put him in the middle of the ball and press B. After that, the ball floats down to Mario so he can spike it again. If Luigi is too close to one of the edges, or if the wrong button (or no button) is pressed, or when Mario fails to spike, the attack stops. This attack, along with the Divided Barrel Gun, uses seven SP.
