Shin Gekijōban ☆ Keroro Gunsō Fukkatsu Shite Sokkō Chikyū Metsubō no Kiki de Arimasu! (New Sgt. Frog the Movie: The Earth Is in Mortal Peril as Soon as We Come Back!), the new 20th anniversary anime film project for the franchise, opened in Japan on June 26. The film ranked at #4 in its opening weekend, earning 150,809,200 yen (about US$927,900) in its first three days.
Crunchyroll added the earlier television anime to its catalog beginning in 2021, and it describes the anime:
Keroro is Sergeant Frog - the leader of a platoon of warriors sent to conquer planet Earth. But when the amphibious invaders discovered how much humans enjoy dissecting their comrades, the troops were scattered, the mission was aborted, and Keroro was abandoned. Now, this once proud soldier spends more time wielding a vacuum than he does the weapons of war. It's a far cry from the glory of battle, but hey, at least he's got his own room. And though the invasion may have slowed to a hop, Sergeant Frog still occasionally yearns to overcome his karaoke addiction and reassemble his troops.
Sunrise's earlier anime series based on Mine Yoshizaki's Sgt. Frog (Keroro Gunsō) manga ran from 2004 to 2011, and it spawned five feature films. Funimation released two "seasons" of the anime on DVD, after ADV Films had licensed but not released the anime.
Discotek licensed the anime, and its release of Sgt. Frog includes all 358 episodes in successive SD Blu-ray Disc volume releases by season, beginning in 2021. Discotek released seasons 5-7 in 2024.
American manga publisher Tokyopop released 20 volumes of the original manga in North America before shutting its doors in 2011.
