Keroro is Sergeant Frog, the leader of a platoon of warriors sent to conquer Earth. When the mission was aborted, Keroro was abandoned. Now, he spends more time wielding a vacuum than he does the weapons of war. Sure, it’s nice that he’s got his own room, but Keroro still occasionally yearns to overcome his karaoke addiction and reassemble his troops. Watch out world, the frogs are taking over.
