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 like Buzzy Beetle Shells on his head like a helmet and become Spiny Mario. They are created by shaking a Spiny in _. Spiny Shells defeat just about every enemy outright on contact; this includes even the tougher enemies, such as Thwomps and Boos, but it only deals a single point of damage to Bowser per hit. When ducking as Small Mario, walking enemies will bounce off Mario as if he was a wall. Spiny Shells can break Blocks like Brick Blocks and Hard Blocks. However, the Spiny Shell is also a double-edged sword in that it's able to break ? Blocks; this in return, means that Mario won't be able to acquire the contents of the ? Block if he hits it from below.

The Spiny Shells can be kicked and act similarly to any other shell that slides along the ground, meaning they can harm Mario on contact while sliding unless Mario touches one from below, in which he will wear the shell. Despite idle Spiny shells being empty, they can still harm Mario, due to the spikes, unless the player holds the dash button when touching one, during which Mario will pick it up, regardless of how he approached it (except in the Super Mario Bros. style).

Once wearing the Spiny Shell, Mario cannot take it off willingly unless he takes damage, or collects a Mystery Mushroom. However, a glitch does exist that allows Mario to wear the Spiny Shell while using the Costume Mario power-up, but it can only be executed in the Course Maker. The glitch was fixed as of version 1.30. In edit mode, Mario can be shaken to remove the Spiny Shell, as well as reverting back to Small Mario if any other power up was given to him.

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