It's Christmas on Pokopen and Keroro wants to celebrate in a special way, but what to do? Spend a quiet evening by the fire? Defend the house from an invasion of super mice? Make gigantic snowmen to destroy all who stand in his way? Star in a new television show? Conquer Earth by turning himself into a 100-foot-tall monster? Let the festivities begin!
