Sgt. Frog , Vol. 12: No-Fly Zone

The invasion continues! Humanity's downfall is imminent! And Natsumi is in a real real bad mood!  When Keroro and Fuyuki deepen their friendship in the tub, Natsumi ends up feeling stuck in the shallow end. But Keroro comes down with a mysterious illness, and it looks like he won't make it! Will our amphibious invader finally croak?! Oh, c'mon--we're not gonna kill off our main characters just yet! Especially when we've got an adventure filled with a big-ass watermelon, a raucous Halloween party, and a jump-rope exhibition in space.  With page after page of merry gambol and leaping adventure, it's enough to make you want to sleep through New Year's!
