A story from the book The Sneetches and Other Stories features The Zax from the Dr. Seuss book. They are stubborn and arguable and have messy hair and hairy bodies. They live in the Prairie of Prax. Varieties of Zax include a North-Going Zax and a South-Going-Zax. Due to their stubbornness, they refuse to go in any direction other than their assigned directions. If a south-going Zax encounters a north-going Zax, they cannot solve their issue and the world progresses without them as years pass by, such as a highway being built over them and a city nearby while still standing grumpily at each other.
