A peaceful country of frogs suddenly faces airstrikes from attack bombers that took off from a floating platform of the devil country. A full force of cat-like creatures stages an attack from sea-planes. General Korokichi the frog issues a battle order with his gun to fight back. Although attack bombers are dispatched from a submarine carrier and attacks intensify at night, the frog team responds with anti-aircraft guns using searchlights. Thanks to Korokichi's outstanding work, the enemy planes are shot down. It is at this point that Korokichi wakes up and realizes that it was all a dream. Source: Japanese Animated Film Classics
