This episode introduced a new on-going member of the Stone family, Coca, an 18 month old standard poodle. While both of his parents are standard poodles, his owner and trainer (Don Wallace), says: "Coca is probably a freak throw back to medieval history. He stands 42.5 inches high, weighs 135 pounds, and has bushy brown hair all over. He resembles a lion from the front, but by nature is as gentle as a lamb."
Mr. Wallace insures Coco for US$100,000 (as of July 21, 1961). Coco travels to work in a white, air conditioned truck equipped for his comfort and safety.
