The Sea Otter is a seaplane employed by the Launcher family for transportation on adventures to ancient ruins. After his father, Asroc, disappeared, Mag Launcher piloted the plane on his own adventures to pay off the family debt. The plane came in handy when Mag flew it to the Imperial Cruiser to rescue Linear Cannon from the clutches of Prince Eugene. Mag's butler, Gre Nade was also able to fly the Sea Otter and performed repairs on it. When not in use, The Sea Otter is parked in the Airfield near Pannam Town.
