Robot Land operates as a theme park where robots, dressed in costumes resembling main characters from children's books, provide entertainment for young visitors. Beneath this cheerful facade lies a hidden underground factory. In this concealed facility, slave robots are compelled to manufacture weapons. The narrative contrasts the innocent appearance of the park with the dark reality of forced labor occurring below ground. This setting establishes a dual nature for the location, serving as both a place of joy for children and a site of exploitation for the robotic workforce.
