The Sgt. Frog anime franchise is based on Mine Yoshizaki’s 1999 manga series of the same name. The original anime adaptation by Sunrise aired from April 2004 to April 2011. A second season aired from March to September 2014. All episodes of the show are available on Crunchyroll via Discotek Media. Crunchyroll describes the series as:
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.
