Near a Town of Fort Knox, Mr. and Mrs. J Carmichael Krox are seen in bed sleeping as their new clock is ticking saving time with not only 2 hands but 3 hands instead and it doesn't tick tock forward but it tock ticks backwards so it saves time and the sleepers can sleep quicker. They might be related to Mr. Knox or Icabod and Izzy, as they have the same dog-like ears and yellow fur.
They are from the book Dr. Seuss's Sleep Book.
