Episode 4 Summary: "Giroro: The Most Dangerous Man in the Universe, Sir!"
: Unlike the lazy and Gundam-obsessed Sergeant Keroro, Giroro is strictly focused on the mission of conquering Pekopon (Earth). He is disgusted by Keroro's domestic lifestyle and sets out to "discipline" the Sergeant and eliminate the Hinatas.
: The episode often also includes a shorter segment where Keroro tries to "help" the Hinata family with chores, such as vacuuming and organizing books, which invariably leads to comedic mishaps. Series Context
