Sunrise’s anime based on the manga of the same name initially ran from 2004 to 2011. It spawned five feature films and two seasons, the latter of which released on DVD via Funimation. Discotek licensed the series and started re-releasing it on Blu-ray in 2021. The anime is available to watch via Crunchyroll, which describes it as follows:
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.
