The Zax are characters from the Dr. Seuss books. 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, such as a highway being built over them.
