Triple Green Shells

Triple Green Shells are clusters of three Green Shells appearing predominantly in the Mario Kart series.

Mario Kart 64
Triple Green Shells first appear in Mario Kart 64. When used, three Green Shells are deployed to orbit the player's kart. The player may throw each Green Shell one-by-one whenever they please, and can also use the Green Shells to block incoming items.

Mario Kart: Super Circuit
Triple Green Shells return in Mario Kart: Super Circuit, behaving exactly the same as in Mario Kart 64.

Mario Kart: Double Dash!!
In Mario Kart: Double Dash!!, Triple Green Shells are among one of the two special items usable by Koopa and Paratroopa; as with all special items in the game, they can also be used by Petey Piranha and King Boo. This is the only game where the Green Shells do not orbit the kart; instead, they are held by the character in the back, though they otherwise function the same.

Mario Kart DS
Triple Green Shells return in Mario Kart DS, behaving the same as in past games. They can be obtained as uncommon items in second through fifth place in Grand Prix and local VS modes, and can also be collected by mediocre and poorly-performing players in Battle Mode; however, they are absent in online VS mode.

Mario Kart Wii
Triple Green Shells return in Mario Kart Wii, behaving exactly the same as in previous games. They can be obtained as uncommon items in second through sixth place in Grand Prix and VS modes; in Battle Mode, they are usually obtained by mediocre-performing players.

Mario Kart 7
Triple Green Shells return in Mario Kart 7, behaving exactly the same as in past games. In Grand Prix and VS modes, they can usually only be obtained in second through fifth place, though sometimes CPUs can obtain them as low as seventh place; in Battle Mode, human players can only obtain Triple Green Shells at or near first place, though CPUs have a fixed probability in obtaining them.

Mario Kart 8 / Mario Kart 8 Deluxe
Triple Green Shells return in Mario Kart 8 and Mario Kart 8 Deluxe, functioning exactly the same as in past appearances. In Grand Prix and VS modes, all players may obtain Triple Green Shells roughly 1000-3500 units from the frontrunner; in Battle Mode, they can be obtained at any point, though they are much more common when the player has only one balloon left at any point in the game.

Mario Kart Tour
In Mario Kart Tour, Triple Green Shells are special items obtainable only by Koopa Troopa, Dry Bones, Iggy, and Lakitu. They function mostly the same, except that they are all fired at once in rapid succession once the player taps the screen.

Mario Kart Wii

 * Trading card description: "A powered-up form of the single Green Shell, when activated, the Triple Green Sells form somewhat of a protective barrier around your vehicle helping you fend off attacks. Then they can be fired, one by one or in rapid succession, forward or backward depending on your needs. A Kart or Bike that comes into contact with a Green Shell will crash and come to a complete stop."
 * Game Tip!: "Activate the Triple Green Shell item as soon as possible. The three Green Shells will protect your vehicle AND you'll be able to pick up another item."

Mario Kart 7

 * Electronic manual description: "Press or  to equip (the three shells spin around your kart), and then press  or  again to throw one shell at a time."

Mario Kart 8

 * Electronic manual description: "Three Shells that spin around your vehicle. Use to throw them one at a time."

Mario Kart Tour

 * Tips & Tricks: "Three Green Shells revolve around your kart. Tap the screen to throw all of them at once and they'll fly in a straight line."
