Paco and Puri Rebollez, siblings, are astronauts in charge of finding and gathering energonia crystals, a material used to power spaceships. To aid them in their hard job, they have special suits equiped with a small thermonuclear cell in the buttocks zone which exhales an invisible gas which Paco and Puri use to rise and fly around. Paco and Puri‘s company has detected an old abandoned ship containing as much as TROPECIENTOS crystals. The siblings could retire if they could gather such a number of crystals, so they decides to ignore the perils they might find inside the ship and begin the search!
