Blue shells first appear in ''[[Super Mario World]]'', either alone or on the back of a Koopa Troopa. As with other colors of shells, jumping on a Koopa Troopa will cause the shell to be removed, where it can then be held or [[Shell Toss|thrown]]. When [[Yoshi]] eats one, he will [[Winged Yoshi|grow wings]] and gain the ability to fly for a limited time, at the end of which he will [[swallow]] the shell. [[Yoshi (species)|Blue Yoshi]] can gain this ability by eating a shell of any color. Yoshis can also spit the shell back out, in which case it will behave like a [[Green Shell]], flying out at high speed and defeating enemies in its way. If the player attempts to launch the shell back at a blue [[Unshelled Koopa Troopa|unshelled Koopa]], it will stop the shell and kick it back at the player. If a green or red unshelled Koopa comes in contact with the Blue Shell (or kicks it right-side up if upside down), it will then jump in it and become that colored Koopa.
