Editing Shell dash

The '''shell dash'''<ref>''New Super Mario Bros.'' instruction booklet, page 24.</ref> is a move that [[Mario]] and [[Luigi]] can perform by entering a [[shell]] and sliding around in it; it can be used in ''[[New Super Mario Bros.]]'' and ''[[Super Mario 3D World]]''. As the player dashes, they defeat enemies and bounce off walls. In the games' multiplayer modes, any other players hit by this move power down or lose a life, depending on their form.

The shell dash is introduced in ''New Super Mario Bros.'' and can be performed only if the player is in their [[Shell Mario|Shell form]] after collecting a [[Blue Shell]]. It can be performed by [[dash|running]] for about two seconds or [[crouch]]ing on a slope. After doing so, Mario or Luigi ducks into his shell and dashes as fast as a moving [[Green Shell]] or [[Red Shell]]. Mario or Luigi can [[jump]] while using this move, as well as hit or break [[block]]s (off which, alongside walls, they ricochet) and defeat enemies; it takes three shell dash hits to defeat most bosses. Unlike when kicking a [[Koopa Troopa]]'s shell and hitting multiple enemies to earn increasing [[point]]s and [[extra life|extra lives]], Mario or Luigi earns only 200 points for every enemy defeated when using a shell dash.

There is a similar move in ''Super Mario 3D World'' and [[Super Mario 3D World + Bowser's Fury|its Nintendo Switch port]]. If the player crouches while holding a Green Shell, they duck into the shell and dash; they remain idle if standing still in the [[Wii U]] version, whereas the [[Nintendo Switch]] version requires using the touch cursor to do so. Unlike in ''New Super Mario Bros.'', one can earn increasing points and extra lives with this move. The player can exit the shell anytime; if they do so, they do a [[Spin Jump]]. However, the player's character automatically exits the shell after a while, becoming dazed and stunned for a few seconds. If a player touches the [[Goal Pole]] while using this move, they get an extra life.

In ''[[Bowser's Fury]]'', [[Fury Bowser]] uses his own version of the shell dash, which involves him tucking into his shell and rolling at Mario from the side of his carapace, rather than have his shell lie flat on the ground. When he does so, he leaves behind a trail of [[goop]], and if [[Giga Cat Mario]] claws his shell or [[Long Jump|long-jump]]s into it, he can be [[Ground Pound|ground-pound]]ed.
