Giant Red Shell

Giant Red Shells are Items found in many of the Mario games. In Super Mario Bros. 3, the red shelled Gargantua Koopa Troopas wear these giant shells, instead of wearing normal Red Shells. These large Koopas would not walk off the edge, unlike the Gargantua Koopas with Green Shells. Instead, they would turn around, and walk on solid ground. Mario could simply jump on these oversized Koopas, and they would hide in their shell, just like a normal Koopa Troopa. Mario could throw these shells, which will then smash into other enemies.

In Mario Smash Football and Mario Strikers Charged Football, Giant Red Shells, as well as their smaller counterparts, are items that players can use. When collected, Giant Red Shells could be shot at the opposing players. It would then home into one of the opposing team members, and spin over him/her, which will squish them, thus, knocking them out for a short while. However, it will only home in once, and after it hits its target, it will just spin around the stage randomly, unlike the normal Red Shells, which home into multiple players, but only hit once.
