Sgt. Frog - S01

The year is 2004, and chaos erupts when strange frog-like aliens swarm the skies with UFOs-or at least, that's what 12-year-old Fuyuki Hinata dreams. By coincidence, Sergeant Keroro, the leader of an advance squad for the Keronian invasion of "Pekopon" (their name for Earth),starts his mission by taking over Fuyuki's house. After overpowering the boy and his sister, Keroro intends to regroup with his team and return to the mothership to fix his crucial invasion tool, the Kero Ball. But he soon learns that headquarters has canceled their retrieval due to a sudden crisis, forcing the rest of the Keronians to retreat. Now stranded, Keroro has no choice but to live with Fuyuki, his sporty but quick-tempered sister Natsumi, and their diligent, charming mother Aki. Day after day, Keroro and his squad scheme to conquer the world, but their plans always fall apart due to unpredictable mishaps. Over time, living among humans changes them, and what starts as an uneasy coexistence turns into genuine friendships-making their unexpected life on Earth surprisingly fulfilling.
