Ezra Jack Keats visits Mister Rogers and reads one his (Keats’) books. In the Neighborhood of Make-Believe, King Friday has lost his XIII. He sends Lady Aberlin and Handyman Negri to search for the “roaming” Roman numeral. Lady Elaine puts a note on the Museum-Go-Round saying, “I didn’t take it.” She leads the neighbors to Donkey Hodie’s windmill. Donkey Hodie has the XIII. The king had offered him 13 for pumping water through the king’s waterfall. Donkey Hodie didn’t want to bother the king for his payment so he took the XIII.
