Shy Guy Swarm is a Captain Command used by Bowser Jr. in Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. It costs 6 CP to use. It can only be used if Bowser Jr. is set to a Flying-type unit. Once activated, Bowser Jr. uses a remote to call in a Shy Guy army, then fly away. Three targets appear and circle the ground, stopping when is pressed. Bowser Jr. then returns with Shy Guy Airtubs, which swoop down and fire cannonballs on the battlefield, damaging all allies and enemies within the radius of the targets.
