Gun-toting, Mutinous Frogs!: It's the dawn of a new school year for Fuyuki Hinata. As if the stress of starting junior high wasn'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?
