Green Shell

In the Mario Kart series, Green Shells appear as a projectile weapon. Racers can shoot Green Shells forward in a straight line to hit opponents. Unlike the Red Shell, the Green Shell is able to rebound from walls. After ricocheting several times, the Green Shell will automatically disappear. Aside from single Green Shells, this item also comes in a triple variant, introduced in Mario Kart 64. When the player decides to use the item, a group of three Green Shells will rotate around the driver's kart (excluding in Mario Kart: Double Dash!!) protecting them from Bananas and other shells. If the player collides with another racer, the other racer will be hit by one, and if the other driver also has another set of Triple Green Shells or Triple Red Shells, both drivers will lose shells. Like ordinary Green Shells, they travel in a straight direction when fired and will bounce off walls for a time. In Mario Kart: Double Dash!!, they are a special item exclusive to Koopa Troopa and Paratroopa (and Petey Piranha and King Boo, due to their ability to have any special item). Also, in Double Dash!!, the three shells are carried rather than having them circle around the kart. Triple Green Shells are not used in Mario Kart DS Wi-Fi mode due to the fact that items cannot be deployed in that mode. As of Mario Kart 64, the Green Shell leaves a green-colored trail when thrown although in more recent games, the trail is more of a blur. Ever since Mario Kart DS, the Green Shell is the emblem of the Shell Cup.
