Sgt. Frog

Sgt. Frog known in Japan as Keroro Gunso (ケロロ軍曹 lit. "Sergeant Keroro") is a harem anime inspired by Storm of Steel, featuring an under-strength platoon of frog aliens that was cut off and encircled from the main army. All of the frogs are horny for a teenage girl, with the horniest being the red one (a corporal, the most sexual rank). The show is a commentary on the horror of war and the benefits of gaming.
