When she gets to the shop, she cannot afford a bowl. The shop owner asks her where her mother is, which appears to sadden her. She passes a school and watches some children singing with their teacher, before returning home for a lonely supper. She awakes the next morning to find the dog outside her house. She takes him with her to visit Chiku-tan and he takes a liking to the portable house, which resembles a kennel. They decide to keep him and name him Saji. The next day, Binchō-tan is invited back to the school and is asked to work there for a day every week. Chiku-tan is walking Saji and he drags her to the school to see Binchō-tan. The children are excited to see him and he takes a special liking to Kunugi-tan. Kunugi-tan is delighted to finally learn Binchō-tan's name. By the end of the episode, Binchō-tan has somehow acquired a bowl for herself and a bowl for Saji.
