Baum gives two different accounts for the piglets origin: * 1: The Piglets are small and white, and are no bigger than mice. They are from the Island of Teenty-Weent where everything is small. The Wizard acquired them from a sailor in Los Angeles in exchange for nine tickets to the circus. * 2:However, Professor and Mrs. Swine, the parents of the nine piglets, met the Tin Woodman and told him that they had given their nine children to the Wizard of Oz so he would care for educate them. In either case, the fact they ended up with the Wizard is undoubted.
