Peptos XI is the planet where Gourmands (Upchuck's species) comes from. It is the 11th planet in the peptos system (and due to the Gourmands unnatural eating habits, possibly the 11th home planet of their species). A once great planet, Peptos XI was once one of the most vibrant planets in the entire universe. Its rich crops, abundant wildlife and diverse spice trade made it the best fed world in the sector. Now a world of dust and gravel, its inhabitants must make do with what is left. After a few years they evolved harder than diamond teeth, four long adhesive tongues and four stretchy stomachs filled with super corrosive acid that can be fired at will with great accuracy. The Gourmands eating habits resulted in them literally eating several of the other planets in their system.
