Overview

Retreats into his shell and spins around. This attack is considered to be one of the best out of shield moves in the game, but only deals up to two hits when used on the ground, making it unsafe to use against enemy shields. As a recovery move, although it gains decent horizontal distance, it gains very little vertical distance, making this recovery worse compared others. On the ground, the clean hit deals good vertical knockback, able to KOing certain characters at around 131%.
