Gun-toting, Mutinous Frogs! It's the dawn of a new school year for Fuyuki Hinata. As if the stress of starting junior high weren't enough, he must also deal with Sgt. Keroro--the froglike alien with apocalyptic intentions--freeloading in his attic. But if Fuyuki thought the Sergeant was a handful, wait'll he gets a load of the rest of the battalion. Members of the Sarge's lost platoon are starting to surface like a plague of frogs, and not all of them agree with the way that Keroro's been running the invasion. When the gun-crazy Corporal Giroro sees the pampered pet that his superior officer has become, will he take control of the mission?
