Although he is best-known for his full-length children's books, Dr. Seuss wrote quite a few shorter stories for children. Three of those stories are collected in Yertle the Turtle and Other Stories, including "Yertle the Turtle," which tells the story of the eponymous Yertle, who happens to be a turtle, "Gertrude McFuzz," which follows the eponymous "girl-bird" Gertrude McFuzz, and "The Big Brag," which tells the story of a rabbit and a bear, both of whom say they are the "best of the beasts."
When it was released, Yertle the Turtle and Other Stories received very positive reviews. Readerslane.com, for example, loved the book and wrote in their review that "The three stories combined take an interesting look at those human foibles of pride, vanity,and boastfulness. In Seuss’ ever-friendly manner they help us look at our own foolishness and the wages of such behaviors."
