Space Detective Kogoro and his sister Lavie land in Pekopon and confuse Natsumi with random comments. They follow Natsumi to the Hinata's house looking for aliens that threaten the peace of Pekopon. The Platoon and the detective fight but only Keroro wants to fight. At the end the fight was staged because Keroro and Kogoro were friends since childhood. Kogoro decides to stay in Earth but it's hard for him to find a job because of his weird actions and speeches. Kululu finds him an audition in a children's program and is actually doing good until Keroro and Tamama feel jealous and jump into the show too.
