In outer space, in a galaxy not far away, there is a peculiar planet: the Great Lentil. It has the shape of a lentil, lots of lentils grow on its surface and its inhabitants, the lentilers, eat this food very often... and fart very much.
The people in the Great Lentil are really excited: for the first time in centuries, they will send a spaceship (shaped as a lentil, of course) to explore the universe. And the heroes in charge of this huge adventure are Captain Lentil and Rufino, his squire cat (who is a little picky). They will travel to planet Earth, a planet which is suffering a terrible drought. Our protagonists will have to discover the mystery behind this... that is, if they are able to stop farting for a while.
