Penguin Village has run out of toilet paper. Now it's up to the village's handsomest hero, Senbei Norimaki, to make the long journey to visit the legendary supermarket in the east. No one knows exactly where it is, so Senbei builds an airplane but it soon falls apart and he crashes. Fortunately, Arale and Gatchan join his quest and they continue traveling east together in search of the supermarket and copious amounts of toilet paper.—shiteatersubs
