Spiny Shell (red)

Spiny Shell is the Spiny variety of Koopa Shells which are worn by Spinies. The shell, however, cannot be picked up or thrown, as Mario and Luigi are unable to jump on it, and throwing another shell at the Spiny defeats it. However, in the GBA version of Super Mario Bros. 3 and also in New Super Mario Bros. Wii, it is possible to carry an upside-down Spiny Shell.

In Super Mario Strikers and Mario Strikers Charged, Red Spiny Shells act as items. When fired, they will shoot towards the other players, acting very similar to the Green Shells. However, instead of just hitting one player, then disintegrating, the Spiny Shells will keep going. This can be compared with the Giant Green Shells. They continue to bounce around the stage until, at long last, they wear out, and get destroyed on their own. The more effective counterpart of the Spiny Shell, is the Giant Spiny Shell. Spiny Shells usually come in groups of three.

In Super Mario Maker and its remake, Mario is able to wear Spiny Shells and Buzzy Beetle Shells on his head like a helmet. It protects him from damage from above, and is useful against Thwomps.

In Paper Mario: Color Splash, there are pits in Kiwano Temple that are filled with spikes that resemble Spiny Shells.
