Mrs. Foreman doesn't mess around. The fourth day of kindergarten and Finn is thrilled to come home with a bag containing Clifford, a few books, and a journal. Apparently he had been the "Special Helper" today and thus got to come home with this special bag.
So he read the stories and set up a special bed for Clifford, even slept on the floor with Clifford. In the morning this is the story he dictated to Jason, about Clifford and some blue guys helping to stop a flood coming into our house. After telling it he acknowledge without any prompting, "This is fiction."
