Gucchan mo Taihen!? Konkon Helmet

Senbei tries to get rid of Arale and Gatchan so he can spend time alone with Midori. He gives Arale money to buy fireworks. A test rocket launched by Arale inspires Nicochan and the servant to come up with a new idea for returning home. They buy all the New Year's Eve rockets they can find, tie them together, and take off.
