The Keroro Platoon rings in the New Year with a bang--and has the hangover to prove it. But underneath the scandal of a liquidly courageous Lady Moa revealing her true feelings for the Sergeant...underneath the threat of a jealous Tamama laying the ultimate smackdown...underneath the Hinata family's inevitable discovery of the mess...is something else.
