This article is about the shells of the Spiny enemy. For information about the Mario Kart item, see Blue Spiny Shell.
Spiny Shells are red spiked Shells worn by Spinies. Mario or Luigi can't jump on the Shell unless they ump on the underside or use Yoshi or a Goomba's Shoe. In Mario Kart games a Spiny Shell with wings called a Blue Spiny Shell is used as an item. It attacks the driver in first place. A spiny shell can also be worn by blue Spinies too, but only have wings.
