In an especially tearful episode, Senbei fixes the anti-gravity device on the Tsun family's rocket, and they leave Penguin Village forever...or at least, for a few pages. And in a sligthly less tearful episode, Senbei fixes the anti-gravity device (again!), this time so that King Nikochan can return home - with some unwanted stwoaways: Arale and the Gatchans!
