Stop and Drop
From the Super Mario Wiki
Stop and Drop is a command that appears in Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. It is only used by Ludwig or Captain and First Officer ranged enemies. The command stops an ally or enemy when they are about to do their Special Skill regardless of whether or not they have Malatone Formula:X, and deals a little bit of damage to them. If used against a group attack, all enemies involved will be stopped and damaged. The command costs Ludwig three Captain Points in order to perform the command; however, if the player selects the command when no enemy is going to use their Special Skill, he loses one Captain Point.
