It may be the end of the world as we know it, but Fuyuki and Natsumi do not feel fine. Of course, it may also be the ultimate opportunity for Keroro to take over the Earth, but even he wouldn't stoop that low. And it may be the perfect day for our Gundam-luvin' green guy to create the ultimate plastic model...of himself! But don't worry, all of this wackiness will eventually simmer down--just in time for an exhausted Hinata household to recieve an unexpected visitor or two from Planet Keron. It's enough to turn anyone into a big, fat baby!
