On the day the Keroro Platoon is due to leave Keron for its mission to conquer Pekopon (Earth), the squad gathers at the space terminal without its sergeant, who has overslept. Enemy forces attack while they wait, leaving Giroro and Zeroro, later known across the main series as Dororo, holding the line until unexpected help arrives. This fifteen-minute short played in theaters alongside the fourth Keroro Gunsou film and fills in the platoon's send-off, before any of them had met the Earthlings they would end up living with.
