The Wonderful Wizard of Oz
Part 1

There was a little girl Dorothy, who lived with her aunt and uncle in Kansas.
One day they were playing outside when suddenly a cyclone started. Dorothy called to her aunt and uncle, but they were not there. She ran into her house and locked herself in her room along with Toto.
Dorothy and Toto opened the front door. It wasn’t Kansas anymore. It was a wonderful green land with strange flowers and the smallest houses.
A woman appeared in front of Dorothy; it was the witch of the north.
She explained that it was the Land of Oz and Dorothy’s house had landed on the top of the wicked witch of the east and killed her. Dorothy was sorry, but the good witch told her that she was a hero for doing it and that she was now the owner of the evil witch’s magic slippers. Dorothy had no interest in magic shoes. She just wanted to come back home. The witch told Dorothy to follow the yellow brick road to the Emerald City and the wizard who lives there could send her home. They went and met a scarecrow in the cornfield. He wanted to get off his pole. Dorothy helped him and they became best friends. He told Dorothy that he wanted to be a great thinker, but he didn’t have a brain. She invited him to come along with her to the Emerald City where the wizard could give him a brain.
