'''Blue Shells''', also known as '''Blue Koopa Shells'''<ref>''New Super Mario Bros.'' Official Nintendo Player's Guide, page 8.</ref>, are blue [[Koopa Troopa]] shells that first appear in ''[[Super Mario World]]'', one of the few games where they are actually worn by Koopa Troopas.

Like other Koopa Troopa shells, the Blue Shell can be launched when the Koopa Troopa wearing it is [[jump]]ed on. It can also be held and [[Shell Toss|thrown]].

==History==
===''Super Mario'' series===
====''Super Mario World''====
Blue shells first appear in ''[[Super Mario World]]'', where they are usually found after jumping on a blue Koopa Troopa, although standalone ones exist as well. When [[Yoshi]] eats one, he will [[Winged Yoshi|grow wings]] and be able to fly for a limited period of time, at the end of which the Yoshi will swallow it. [[Yoshi (species)|Blue Yoshi]] can use this ability from any shell color.

====''New Super Mario Bros.''====
In ''[[New Super Mario Bros.]]'', the Blue Shell is a power-up. It turns [[Mario]] or [[Luigi]] into [[Shell Mario]] or Shell Luigi, respectively (upon collecting it or [[Ground Pound|ground pounding]] the Koopa Troopa wearing it). The item can be collected by defeating a wandering [[Hammer Bro]] (or stomping the Blue Koopa Troopa found only in one level of the multiplayer mode), hitting a [[Flying ? Block|Flying ? Block]], or getting one from a [[Toad House|Red Toad House]] or [[Roulette Block]]; however, it cannot be found in any of the normal [[? Block]]s in the game. When ducking, Shell Mario/Luigi is invulnerable to almost anything. Also, they can [[shell dash]], allowing them to complete tasks (such as breaking blocks in particular locations) that would normally require a thrown Koopa Shell to achieve. Some obstacles can also only be passed by using the shell dash. Additionally, the power-up allows them to swim faster and with more precision.

The ''New Super Mario Bros.'' Prima guide has an icon for Blue Shells in the map legend, but it is not used in the entire guide.

====''Super Mario Galaxy''====
In ''[[Super Mario Galaxy]]'', if [[Cosmic Mario]] picks up a Koopa Shell during [[Underwater Cosmic Mario Race|his race]] in the [[Sea Slide Galaxy]], it will become a blue shell.

====''Super Mario 3D World''====
Though the Blue Shell itself does not appear in ''[[Super Mario 3D World]]'', players can jump on a Koopa Troopa and steal their shell; when [[shell dash|using it]] as [[Toad]] or [[Rosalina]], the shell color turns dark blue (Toad) or light blue (Rosalina), very much like the Blue Shell in ''New Super Mario Bros.''

====''Super Mario Odyssey''====
In ''[[Super Mario Odyssey]]'', a blue shell is worn by the Trace-Walking Koopa in the [[Snow Kingdom]], as well as one of the [[Roving Racers]]. Aside from the gold-shelled racer who is limited to the Master Cups, this one is consistently the fastest of the Roving Racers, and as such is the fastest in the Regular Cups.

===''Paper Mario'' series===
[[Kooper]] from ''[[Paper Mario]]'' utilized a blue Koopa shell, which was initially stolen by [[Fuzzy|Fuzzies]] before being retrieved by [[Mario]]. Although the next playable Koopa Troopa character, [[Koops]] in ''[[Paper Mario: The Thousand-Year Door]]'', does not possess a blue shell himself, his father [[Koopley]] does, as did [[Kolorado]]'s [[Kolorado's father|father]]. The Blue Koopa shell apparently is capable of resisting stomach acids from within [[Hooktail|a dragon]]'s stomach tract for a long period of time, as evidenced by Koopley surviving being eaten by Hooktail by staying in his shell.

===''Mario Strikers'' series===
In ''[[Super Mario Strikers]]'', as well as in ''[[Mario Strikers Charged]]'', Blue Shells appear as items; they appear as ice-frosted-over cyan shells in the latter game. They are usually collected in a pack of three. When used, they will be fired at the opposing players, however, they do not home in, like the Red Shell does. If the Blue Shell happens to hit a player, they will instantly freeze in one spot. This will render them unable to move, and, thus, unable to get the ball. The effects wear off after a few seconds. Unfortunately, these shells can freeze both the user's teammates, or the user. If the shells fail to hit anyone, they will continue bouncing around the stage until they either hit a player, or just wear out on their own. A more effective version of this item is the [[Giant Blue Shell]].

===''Mario & Luigi: Bowser's Inside Story'' / ''Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey''===
The Blue Shell appears in ''[[Mario & Luigi: Bowser's Inside Story]]'' and [[Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey|its remake]], as an item found in the overworld and once in the [[Energy Hold]] in Bowser's Body. Mario can go in Blue Shells (and turn into Shell Mario from ''New Super Mario Bros.'') by striking [[Shell Block]]s. Luigi can then hit Mario using his [[hammer]], and this will make Mario go into the shell, spinning straight forward. This can be used to hit blocks in areas which Mario and Luigi can't directly go into. To toss the Blue Shell, Mario must jump. It behaves similarly to [[Kooper]] and [[Koops|Koops's]] abilities in the [[Paper Mario (series)|''Paper Mario'' series]].
