The plot of Welcome to the Space Show is: Welcome to the Space Show, whose story "surpasses Star Wars in its scale" according to its producers, tells of the four adventures of five schoolmates and an alien dog in space during summer vacation.[2]
The plot revolves around five elementary school kids on their "school trip". In the process of looking for their missing class pet (a rabbit named Pyon-Kichi), the children rescue a dog they find injured in a corn field. The dog turns out to be an alien called Pochi Rickman, and he invites them to visit the moon as a reward for helping him. However, through a series of strange events, they become stranded and must make their way across the galaxy to get to Pochi's homeworld, Wan; so that they may return to Earth. Along the way they are pursued by the aliens responsible for Pochi being injured in the first place. The aliens work for the host (called Neppo) of the universe's most popular entertainment, "The Space Show", which appears to be a variety act broadcast from a mysterious moving spaceship.
Neppo is bent on using the power of the ship, called the Pet Star, to become a god. However, the ship requires a particular power source to run; namely a substance called Zughan, which turns out to be a close relative of the wasabi root. As Natsuki is carrying some of the root with them in her bag, Neppo has thus targeted the group. When his thugs fail to retrieve the bag, Neppo goes himself; arriving just as the children and Pochi reach Wan. The Pet Star's tractor beams steal the bag, but they also take Amane as well.
This leads to a show down at an interstellar festival, where with the help of friends they've made along the way, the children manage not only to defeat Neppo and rescue Amane but also save the entire universe. The children are then able to return home (along with Pyon-Kichi, who had been kidnapped by Neppo's henchmen as well) and arrive at the school just before their parents show up to retrieve them..
