The Shaggy Man of Oz (1949) is the thirty-eighth in the series of Oz books created by L. Frank Baum and his successors, and the second by Jack Snow. Jack Snow modernised Oz, so this book has airplanes and TV screens, but he otherwise based his work strictly on Frank Baum’s original material.
Abbadiah and Zebbidiah Jones are twins from Buffalo, New York; they prefer to go by their nicknames, Twink and Tom. While the twins are watching the TV one afternoon, the normal picture changes into a strangely beautiful scene with a castle in the background. They are confronted by a living toy clown, a duplicate of the familiar toy they have named Twoffle. This living version, who calls himself Twiffle, persuades them to walk into the screen before them; the two children find themselves magically transported into Oz where they meet Princess Ozma, the Nome King, the King of the Fairy Beavers and many other beloved places and characters from Frank Baum’s original Oz books, and some from “John Dough and the Cherub” also by Frank Baum.
