Some stories are basically self-conscious parodies of romantic novels about knights, with more profound issues of psychology and social dynamics under a cartoonish and swashbuckling facade. Three of them were published in an earlier collection, Fables for Robots.
A typical example is the fairy tale O królewiczu Ferrycym i królewnie Krystali) ("Prince Ferrix and the Princess Crystal"). A princely (robotic) knight falls in love with a beautiful (robotic) princess. Unfortunately, the princess is somewhat eccentric, and is captivated by stories of an alien non-robotic, "paleface" civilization (the humans). She declares that she will only marry a "paleface". Therefore, the knight decides to masquerade as a paleface. He covers himself with mud, starting to resemble one, and then comes to woo her.
Meanwhile, a real "paleface" captive arrives, given as a gift to the king. It immediately becomes obvious to the princess who is the "muddier" one, but the "paleface" turns out to be too squishy and overall disgusting. Not wanting to back down at the last minute, however, the princess declares a joust between the two suitors to select the worthier one. When the "paleface" charges at the robot, he splatters himself on the latter's metal chest, revealing the metallic body to all. The princess, beholding the beauty of the exposed robot (compared with the ugliness of the "paleface"), changes her mind. The knight and the princess live happily ever after.
