It is created when a yellow [[Unshelled Koopa Troopa|unshelled Koopa]] climbs into an empty shell of any color (including its own, after being ejected from it). After its transformation, the shell attempts to hit [[Mario]] or [[Luigi]] by spinning around and dashing towards him. It becomes impossible to separate the Koopa from it. While chasing the player, the flashing shell defeats enemies in its path; the player scores a combo in increasing [[point]] values for successive enemies defeated by a single flashing shell and [[extra life|extra lives]] starting on the eighth. It is possible to respawn the yellow unshelled Koopa that climbed into the shell, possibly leading to it dodging its own shell.
