'''Green Shells''' (also formatted as '''green shells''')<ref>{{cite|url=youtu.be/OgoMjdXAuO8|date=June 25, 2022|title=EPIC Mario Kart Takedowns Compilation 🙌💥 {{!}} @playnintendo (Chapters)|publisher=YouTube|accessdate=April 26, 2023|language=en-us|author=Play Nintendo}}</ref> are a common variety of [[Koopa Shell]]s. Though their appearance remains largely the same, Green Shells are occasionally differentiated from those of other colors of shells.

==History==
===''Super Mario'' series===
====''Super Mario World''====
Green Shells make their first appearance with a notable behavior difference in ''[[Super Mario World]]''. However, instead of the Koopa Troopa retracting back into its shell, it will slide out of its shell, becoming an [[Unshelled Koopa Troopa|unshelled Koopa]]. If the unshelled Koopa finds its shell again, it will go back inside it. Green Shells do not give [[Yoshi (species)|Yoshis]] who eat them any additional abilities, unlike the other shells.

Once [[Fall]] is unlocked by beating [[Funky (level)|Funky]] in the original game, or by [[Completion|clearing all 96 exits]] in ''[[Super Mario World: Super Mario Advance 2]]'', all Green Shells become green-colored Mario masks but otherwise function the same; many instances of Green Shells and Koopa Troopas are also replaced with [[Yellow Shell]]s and Yellow Mask Koopas, though green variants of each can still be found.

====''Super Mario Galaxy''====
Green Shells reappear in ''[[Super Mario Galaxy]]'' as an offensive weapon. Many Green Shells in the game will be found independently (usually underwater), though occasionally they will still be attached to the back of a Koopa Troopa, in which case the player must [[spin]] the Koopa Troopa or [[jump]] on its back to get it to retreat into its shell, after which it can be picked up and used normally. Mario can throw the shell by spinning in a straight direction until it hits another object. Similar to in the ''[[Mario Kart (series)|Mario Kart]]'' series, the Green Shell moves in a straight line, and keeps going even if the Green Shell is thrown off the edge of a planet.

====''Super Mario Galaxy 2''====
[[File:SMG2 Slimy Spring Snoodle Cavern.png|thumb|Luigi near a Green Shell in the Slimy Spring Galaxy]]
Green Shells reappear in ''[[Super Mario Galaxy 2]]'', with the same function as in the predecessor. However, in this game, only Green Shells appear, and [[Red Shell]]s and [[Gold Shell]]s do not. In this game, they are mostly found in galaxies such as the [[Cosmic Cove Galaxy]] and [[Slimy Spring Galaxy]].

====''Super Mario 3D Land''====
Green Shells reappear in ''[[Super Mario 3D Land]]'' with a function similar to the 2D ''Super Mario'' games. However, they bounce off each other upon colliding, and fireballs, boomerangs, and the [[Statue Mario|Statue form]] only stop them. If the player manages to keep a Green Shell in the air hitting it five times with a projectile from a [[Fire Flower]] or [[Boomerang Flower]], or with a tail whip from a [[Super Leaf]], it will turn into a [[1-Up Mushroom]].

===''Mario Kart'' series===
[[File:MKW Green Shell Artwork.png|thumb|140px|The Green Shell in ''[[Mario Kart Wii]]'']]
Green Shells are projectile weapons in the ''[[Mario Kart (series)|Mario Kart]]'' series. 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 automatically disappears. Green Shells can be obtained in first to fourth place in ''[[Mario Kart DS]]'' and ''[[Mario Kart 7]]'', as well as first to fifth place in ''[[Mario Kart Wii]]''.

Aside from single Green Shells, this item also comes in a [[Triple Green Shells|triple variant]], introduced in ''[[Mario Kart 64]]''. When the player decides to use the item, a group of three Green Shells rotates around the driver's [[kart]] (excluding in ''[[Mario Kart: Double Dash!!]]''), protecting them from [[Banana]]s and other shells, though not always. 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 bounce off walls for a time. In ''Mario Kart: Double Dash!!'', they are a special item exclusive to [[Koopa Troopa]] and [[Koopa Paratroopa|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'' [[Nintendo Wi-Fi Connection|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]].
====''Super Mario Kart''====
[[File:SMKGreenShell.png|frame|left]]
In ''[[Super Mario Kart]]'', the Green Shell is an item in the form of a missile. When the player uses this item, it fires directly forward of the player's kart, changing direction only if it hits a wall. Alternatively, the player can place the shell on the track behind them like a Banana. The Green Shell is destroyed once it hits a kart or another item, or falls off the racetrack or into water or lava. If the shell has not been destroyed or fallen off the track, the game engine will remove it after more items are released onto the track. When a kart is hit by a Green Shell, the kart stops dead in its tracks whilst spinning out, unlike with a Banana, where it continues to move for a short while. The only computer-controlled player with the ability to use a Green Shell is [[Koopa Troopa]], but instead of Koopa Troopa throwing the shell, it is thrown through the air in the same manner as a Banana, and it stops suddenly when it lands rather than sliding across the ground. Green Shells do not bounce over [[ramp|jumps]]. For example, firing a Green Shell towards the main jump on [[SNES Mario Circuit 2|Mario Circuit 2]] makes the shell bounce back after hitting the wall, rather than clearing the jump and landing on the track section over the wall.

====''Mario Kart 64''====
[[File:GreenShellMK64.png|frame|left]]
In ''[[Mario Kart 64]]'', the Green Shell (named '''Torpedo Shell''' on one occasion)<ref>{{cite|date=April 1997|publisher=Catalyst Publishing|language=en-au|title=''Nintendo Magazine System'' (Australia) issue 49|page={{file link|NMS Australia 49 MK64 drivers and items.jpg|39}}}}</ref> acts the same way as in the previous game; however, when the player holds the analog stick backwards, the shell now gets fired backwards instead of dropped. Computer-controlled opponents do not receive this item in the game, their items being relegated to Bananas, Boos, [[Fake Item Box|Fake Item]]s, [[Super Star]]s, and [[Lightning|Thunderbolt]]s. When a player is hit by a Green Shell, they flip multiple times for roughly two seconds before stopping. This crash effect also affects the computer-controlled players while offscreen, whereas a computer opponent being hit with a [[Red Shell]], a Fake Item, a Star, or a [[Chain Chomp|Chomp]] (the latter being only on [[N64 Rainbow Road|Rainbow Road]]) offscreen simply makes the computer-controlled player stop and continue to move immediately afterwards in the form of a cheat.

An alternate item called the Triple Green Shell also debuts in ''Mario Kart 64''. When this item is activated, three shells form a circular barrier around the player's kart in a similar way to the balloons in [[Battle Mode]] in the previous game, and the shells can be used to guard against items and projectiles, as well as turning the kart into a battering ram against other karts. Unlike the single Green Shell, however, these shells cannot be fired backwards and are slightly harder to aim as they are constantly rotating around the kart.

====''Mario Kart: Double Dash!!''====
In ''[[Mario Kart: Double Dash!!]]'', the Green Shell can be destroyed after hitting a certain amount of walls. Also, when fired backward, it moves much slower than forward, unlike ''Mario Kart 64'' where the shell moves at the same speed in both directions. The physics has also been changed from the previous game, and being hit by a Green Shell will simply topple the player's kart, letting them continue moving straight away. The Triple Green Shells also reappear in this game, but only [[Koopa Troopa]], [[Koopa Paratroopa|Paratroopa]], [[Petey Piranha]] and [[King Boo]] can get this item, as it is now classified as a [[Special Item (Mario Kart series)|Special item]]. Unlike ''Mario Kart 64'' however, instead of the shells rotating the player's kart, they are held in the character's hand, and as such, they cannot be used as protection against track-based obstacles unless they are fired. Also, a shell will travel through a Fake Item Box without destroying either of the two. Also, the Triple Green Shell can now be fired backwards, a feature missing from ''Mario Kart 64''. Characters who otherwise cannot receive Triple Green Shells can steal this item from another kart by ramming it while using a [[Mushroom]]. Also, computer-controlled racers can now receive, and fire, any item in the game from any position. In this game, the Green Shell has a sound effect similar to [[Spiny Shell (blue)|Spiny Shell]]s from ''Mario Kart 64''.

Non-moving Green Shells also make their first appearance since ''Super Mario Kart''. If a player holding a Green Shell or Triple Green Shell is hit by a [[Spiny Shell (blue)|Spiny Shell]], a [[Bob-omb]], [[Lightning]] or a [[Super Star|Star]], the shell(s) will be dropped onto the track. [[Yoshi's Egg]]s and [[Birdo's Egg]]s may also randomly release this item after being destroyed. Certain course obstacles may also make a kart lose their items, such as Piranha Plants, Chain Chomps, [[Cataquack]]s and cars and trucks. Also, certain creatures on some race tracks can be temporarily taken out by shells, such as Goombas and Cataquacks. If a pipe containing a Piranha Plant is hit, the Piranha Plant droops down and temporarily cannot attack passers-by.

====''Mario Kart DS''====
Green Shells are items in ''[[Mario Kart DS]]''. They function mostly the same way as it did in ''Mario Kart: Double Dash!!''. Both single and triple Green Shells are now part of the standard item rotation. Notably, Green Shells are smaller than they were in previous games, as with several other returning items, and do not have a trail when fired. They can be fired forwards or backwards, and will be dropped onto the ground if the racer is hit while preparing to throw one, or while in the inventory if hit by any item which forces the racer to drop their items, where they behave like they did in ''Mario Kart: Double Dash!!''.

====''Mario Kart Wii''====
Green Shells are items in ''[[Mario Kart Wii]]''. Green Shells do not have any significant changes, though their size has been increased again, and they once again have trails behind them when fired.

====''Mario Kart 7''====
Green Shells are items in ''[[Mario Kart 7]]''. They have no distinctions in this appearance. However, unlike the previous games where they move slower when fired backwards, here they move faster backwards than forwards.

====''Mario Kart 8''====
In ''[[Mario Kart 8]]'' and ''[[Mario Kart 8 Deluxe]]'', Green Shells return once again. However, they have received some changes. Most notably, Green Shells have been increased in size yet again, now being as big as some of the smaller vehicles. In addition, Green Shells now have hitboxes that trail behind the shell, such that a direct hit is no longer required for a racer to be hit by one, especially when bouncing back and forth perpendicular to the track. Adding to this is the fact that the bounce pattern of Green Shells is now less predictable, due to walls on tracks generally being rougher and more elaborate than the smoother straight or curved walls from previous games, resulting in Green Shells bouncing at unexpected angles off of walls.

====''Mario Kart Tour''====
Green Shells appear as an item in ''[[Mario Kart Tour]]''. They can appear as one shell, or triple shells, and can be launched either forwards or backwards. They can also be used as a form of defense against many other items. They can also slow down an opponent by letting the opponent ram into a player holding a green shell on the back.

The Triple Green Shells reappear as a special item in this game, usable only by Koopa Troopa, [[Dry Bones]], [[Iggy]], [[Toad (species)|Green Toad (Pit Crew)]], [[Lakitu]], [[Shy Guy|Green Shy Guy]], [[Roving Racers|Koopa (Freerunning)]], and the [[Mii|Green, Dry Bones, and Iggy Mii Racing Suits]].

The following gliders increase the chance of getting Green Shells and points for hitting racers with one.

Green Shells are items in the [[Super Smash Bros. (series)|''Super Smash Bros.'' series]]. It can be picked up and thrown at other fighters, damaging them. The shell can also be activated by hitting it or jumping on top of it, which causes the shell to shoot in a certain direction, damaging any characters in the way.

===''Mario Tennis'' series===
Green Shells are items in the [[Nintendo 64]] version of ''[[Mario Tennis (Nintendo 64)|Mario Tennis]]'' for the [[Nintendo 64]] and ''[[Mario Power Tennis]]''. These staples can be used during an Item Battle match, which can be obtained when the player hits an [[Item Box]] with the ball over the net. If the player hits the ball after receiving the item, three green shells are fired at the same time towards the opponent's side of the court to stumble them so that they cannot receive the incoming ball. Just like in other games, green shells go in straight lines, but if they cannot hit any target on their way, they simply disappear after being used. In ''[[Mario Tennis Open]]'', tennis gear is designed based on this item, and available for [[Mii]]s to use.

====''Mario & Luigi: Partners in Time''====
[[File:M&LPiT Green Shell group artwork.jpg|thumb|left|Artwork of the Green Shell from ''[[Mario & Luigi: Partners in Time]]'']]
In ''[[Mario & Luigi: Partners in Time]]'', the Green Shell is a [[Bros. Item]] that is used as a weapon against enemies. At least two bros. are required to use the item. When the item is chosen, one of the brothers will kick the Shell towards the foe. It will then bounce off the enemy, cause damage, and come to the other player. After each kick, the shell starts moving faster along the ground. The brothers can then repeat this until the player misses a kick, the enemy is defeated, or sixteen successful hits are dealt; in any one of these cases, the Green Shell disappears. When the adult and baby Mario brothers fight together, the babies can sit over the shell and spin upon pressing the corresponding button the babies use, causing extra damage to the foe.

====''Mario & Luigi: Bowser's Inside Story'' / ''Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey''====
[[File:MLBiS Green Shell.png|thumb|left|How to use the Green Shell in ''[[Mario & Luigi: Bowser's Inside Story]]'']]
In ''[[Mario & Luigi: Bowser's Inside Story]]'' and its [[Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey|Nintendo 3DS version]], the Green Shell is a [[Bros. Attack]] for Mario and Luigi. To use it, the player must get all the [[Trash Pit]] [[Attack Pieces]]. This is the first Bros. Attack the brothers get, as well as one of the few mandatory ones. It is used exactly as in ''Mario & Luigi: Partners in Time'', but lacks the baby-button command. Unlike the previous game, the shell moves faster as it gets kicked and slows down slightly after it ricochets from the enemy, though the returning speed of the shell still increases after each kick. This shell will continue to attack even if the first target was defeated, just like the [[Red Shell]] in ''Mario & Luigi: Partners in Time'', and will break after ten hits. It costs three SP to use this attack.

In the remake, the number of hits has been reduced to six, and the finishing attack is similar to that of the 3D Green Shell in ''[[Mario & Luigi: Dream Team]]'' and the [[Red Shell#Mario & Luigi: Dream Team|3D Red Shell]] in that game and ''[[Mario & Luigi: Paper Jam]]''.

Among a series of images in the game's credits showing a battle between the brothers and Bowser, one displays the pair using this attack.

====''Mario & Luigi: Dream Team''====
[[File:MLDT3DGreenShell.png|thumb|left|Mario and Luigi performing the 3D Green Shell Bros. Attack]]
The Green Shell reappears as the first of Luigi's [[Bros. Attack]]s in ''[[Mario & Luigi: Dream Team]]'', under the name '''3D Green Shell''' and like the [[3D Red Shell]], it costs 4 [[Bros. Point|BP]] to be used. The Attack Pieces to obtain the 3D Green Shell are found in Mushrise Park, which are given to Luigi after Mario and Luigi free [[Brickle]] from the fountain. It can only target enemies on the ground. Unlike its [[3D Red Shell|counterpart]] used by Mario, the 3D Green Shell hits enemies more randomly and Luigi initiates and ends the attack.

Upon using the attack, Mario and Luigi will both run into the foreground, where Luigi will take out a Green Shell and kick it at one of the enemies. Mario will kick the Green Shell back at the enemies after it rebounds off the enemy towards him, and Luigi will do the same, this repeating three more times. After the Green Shell hits nine times, Mario will then kick the Green Shell towards Luigi, who blasts it at one of the enemies, ending the attack. If all enemies are defeated before the attack ends during it, the attack will end prematurely at that point, rendering it impossible to get an "Excellent!!" rating.

Striking three, five, nine and ten times with the Green Shell yields an "OK", "Good!", "Great!!" and "Excellent!!" rating respectively.

This attack is used in the [[Mad Skillathon]], functioning like the main version, except the passing is not done, and each kick nets three points.

Outside of the Bros. Attack, Green Shells are found in the [[Junior Clown Car]]. When Mario and Luigi steal the car from [[Bowser Jr.]], they are one of the objects available to throw at him.

==== ''Mario & Luigi: Brothership'' ====
Luigi can perform this attack once again as his first Bros. Attack in ''[[Mario & Luigi: Brothership]]'', with the BP cost being increased to 5. It is received alongside the Red Shell on [[Shipshape Island]] after defeating [[Gorumbla]]. The final kick now causes the shell to swerve and strike every grounded enemy at once.

Striking one, three, five and six times with the Green Shell will yield an "OK!", "Good!", "Great!" and "Excellent!" rating respectively.

===''Mario Strikers'' series===
[[File:Green_Smash_Football_Shells.png|thumb|left|Green Shell icon in ''Super Mario Strikers'']]
Green Shells, as well as the green [[big shell|Giant Shell]]s, are offensive power-ups in ''[[Super Mario Strikers]]'' and ''[[Mario Strikers Charged]]''. In these games, they are normally collected in groups of three. Once used, they are fired out in the direction the soccer player is facing. The Green Shell then trips up any opponent it hits on the ground, thus halting their movements for a small period of time. The shells, unlike the [[Red Shell]]s, do not home in on a target, but instead move in one straight path until the shell hits a wall, which makes them bounce back, or hits a player, which destroys the shell. The aforementioned Giant Shells cover a wider range than the regular Green Shell. They are useful for clearing room for a [[Super Strike]] or [[Mega Strike]].

===''Mario & Sonic'' series===
====''Mario & Sonic at the Olympic Games''====
Green Shells appear as an item in [[Dream Race (Mario & Sonic at the Olympic Games for Nintendo DS)|Dream Race]] in the [[Nintendo DS]] version of ''[[Mario & Sonic at the Olympic Games (Nintendo DS)|Mario & Sonic at the Olympic Games]]'', and function almost identically to the shells in ''Mario Kart'' games, although they can only be thrown forwards in this event. Characters will lose speed if hit by one, although their effect can be blocked with a [[Barrier (Sonic the Hedgehog)|Shield]]. They also appear in [[Dream Canoe]], where they come in sets of five with almost the same function, although they instead cause the character hit to lose three coins, and can either be jumped over or have their effect blocked by a Starman item. They also appear as an item in [[Dream Long Jump (Mario & Sonic at the Olympic Games)|Dream Long Jump]], with the same effect as in Dream Race, but additionally cause the player to lose height and can be blocked by a [[Super Star|Starman]]. A Green Shell also appears in [[Shoot!]], where it is used by the player to hit various enemies.

In the [[Wii]] [[Mario & Sonic at the Olympic Games (Wii)|version]], Green Shells appear as an item in [[Dream Race (Mario & Sonic at the Olympic Games for Wii)|Dream Race]], where they can be thrown straight forward and can either hit an obstacle on the course or an opponent. They can be defended against using a Starman or by jumping over them.

====''Mario & Sonic at the Olympic Winter Games''====
Green Shells are items in [[Dream Alpine (Individual)|Dream Alpine]], [[Dream Ski Cross (Individual)|Dream Ski Cross]], [[Dream Snowboard Cross (Individual)|Dream Snowboard Cross]], [[Dream Short Track]] and [[Dream Bobsleigh]] in the [[Wii]] version of ''[[Mario & Sonic at the Olympic Winter Games (Wii)|Mario & Sonic at the Olympic Winter Games]]'', where they can be thrown forwards to knock down any opponents in their path, causing them to lose speed. They can be blocked using either a Super Star or Shield. They also appear as an item in [[Dream Ice Hockey]], where they cause the puck to be turned into a Green Shell, allowing for faster and more powerful shots to be made. In the [[Dream Gliding (Individual)|Individual]] and [[Dream Gliding (Team)|Team]] versions of Dream Gliding, an unlimited supply of Green Shells appear as the main projectile that players use to shoot the [[Egg Flapper|Flapper]]s.

====''Mario & Sonic at the London 2012 Olympic Games''====
During the [[Dream Hurdles]] event in the [[Wii]] version of ''[[Mario & Sonic at the London 2012 Olympic Games (Wii)|Mario & Sonic at the London 2012 Olympic Games]]'', two Green Shells can appear if the player pushes a ? Switch; getting hit with one results the player losing five points. A [[List of badges in Mario & Sonic at the London 2012 Olympic Games (Nintendo 3DS)|badge]] featuring both a Green Shell and a Red Shell can be obtained from the badge machine in the [[Mario & Sonic at the London 2012 Olympic Games (Nintendo 3DS)|Nintendo 3DS version]].

====''Mario & Sonic at the Sochi 2014 Olympic Winter Games''====
In ''[[Mario & Sonic at the Sochi 2014 Olympic Winter Games]]'', Green Shells appear in [[Snow Day Street Hockey]], where [[Pianta]]s will occasionally throw them out on the Main Street rink in the place of pucks if the puck is hit into their box. The Green Shells act similarly to pucks but move faster and have a stronger rebound from walls.

====''Mario & Sonic at the Rio 2016 Olympic Games''====
Green Shells appear in [[Rhythmic Gymnastics Plus]] in the [[Nintendo 3DS]] version of ''[[Mario & Sonic at the Rio 2016 Olympic Games (Nintendo 3DS)|Mario & Sonic at the Rio 2016 Olympic Games]]'', where they appear occasionally to uncover upcoming buttons. They also appear as an item in [[Football Plus]], where one will replace the ball and increase the power of all of the team's shots until the other team gains possession of the ball.

===''Mario Super Sluggers''===
Green Shells are items in ''[[Mario Super Sluggers]]''. The offense side can use them the batter has [[Chemistry]] with the on-deck character. Green Shells travel in a straight line and can knock away any players it hits. Green Shells break upon hitting walls or other obstacles.

===''Mario Sports Mix''===
Green Shells are items in ''[[Mario Sports Mix]]''. They move at a straight line when used and temporarily knock out whoever is in their path. When combined with a ball/puck, the Green Shell moves in a straight line at high speeds.

===''The Super Mario Bros. Movie''===
[[File:TSMBM Green Shell.jpg|thumb|A Green Shell in the Rainbow Road scene]]
In ''[[The Super Mario Bros. Movie]]'', during the [[kart]] chase on [[Rainbow Road]], a large Koopa vehicle with a cannon fires a Green Shell at the Kongs' vehicles which begins ricocheting off some of them. Mario also uses one against a large Koopa vehicle after losing his kart to Bullet Bills and commandeering a small Koopa vehicle.

===Other appearances===
Green Shells are a recurring furniture item in the ''[[nookipedia:Animal Crossing (series)|Animal Crossing]]'' series. In ''[[nookipedia:Animal Crossing|Animal Crossing]]'', they are named "[[nookipedia:Item:Koopa shell (Animal Crossing)|koopa shell]]," formatted in lowercase, and have a design based on their appearance in ''[[Super Mario Bros.]]'' In ''[[nookipedia:Animal Crossing: Wild World|Animal Crossing: Wild World]]'', the [[nookipedia:Item:Koopa shell (Wild World)|koopa shell]] is the same as in ''Animal Crossing''. However, in ''[[nookipedia:Animal Crossing: New Leaf|Animal Crossing: New Leaf]]'', they were consistently renamed to [[nookipedia:Item:Green Shell (New Leaf)|Green Shells]] and given a depiction based on their other appearances around the time. In ''[[nookipedia:Animal Crossing: New Horizons|Animal Crossing: New Horizons]]'', it is simply named "[[nookipedia:Item:Shell (New Horizons)|Shell]]," but now appears in green and red varieties.

In [[Super Mario Chess|''Super Mario'' Chess]], Green Shells appear as pawns on Bowser's team.

If the [[? Block|Question Block]] AR Card is used in the Fishing minigame included as part of the [[AR Games]] software on the [[Nintendo 3DS]], and the card is placed on a green surface, Green Shells will rain down upon the water. The shells can also be caught by the player.

In ''[[Monopoly Gamer]]'', there is a Green Shell side on the "Power-Up Die". Rolling it normally forces the next player on a space forward from the player's position (player's choice if multiple players occupy the space) to drop three Coins on that space, where the next player who lands on or passes that space can pick them up. Some characters have a "Power-Up Boost" that enhances or changes this power.

In ''[[Minecraft]]'', Turtle Shells are changed to resemble Green Shells in the Super Mario Mash-up.

|desc=Hit or throw a Green Shell, and it'll follow the contours of the environment, causing heavy damage to any characters it hits. These Koopa shells have many uses in the Mario series: they've been picked up, kicked, swallowed and even spit out. Mario just uses them as tools to pummel Bowser's numberless henchmen.

|desc=An item that, when thrown or jumped on, careens across stages and hurts any player it hits. Green shells follow the environment's contours as they go and reverse direction when they hit walls. They really send opponents flying, so they're very effective as throwing weapons. If a shell's approaching, stop it by jumping on it. This technique is used in the Mario series.

|desc=The green shell of the Koopa Troopas. The launching power of this weapon is incredible in the right hands, but you should be careful; if it hits a wall, it may bounce back toward whoever threw it. If you see it coming back at you, just jump on it to stop it. It's like playing Super Mario Bros.!
|desc2=You might have noticed these shells look a lot like the ones Koopas have. Throw, attack or jump on one to send it careening off, launching enemies and causing chaos as it goes. Then jump on it to bring it to a stop, or let it rebound off a wall, or... Hold on! What is this? Super Mario Bros.?
