Spiny Bombshell

The Spiny Bombshell is an item that debuts in Mario Kart Twinsanity. It serves as a replacement for the Blue Spiny Shell in that game, and it is a more powerful and faster version of the aforementioned item. The Spiny Bombshell travels twice as fast as the Blue Spiny Shell, and the only way to avoid it is to use a Starman or a Boo.
