Dorothy Gale grew up on a farm in a one room farmhouse with Aunt Em, Uncle Henry, her dog Toto, and four other farmers to help around the farm. She was only 12 years old when she got swept up by a huge tornado.
When Dorothy went up in the tornado she saw many things like the Wicked Witch of the West on her bike, farm animals, people in the bath, and nighboors bringing over food to the Gale's house.
Before all of this happend Dorothy was mad at Aunt Em and Uncle Henry because the Wicked Witch of the West wanted Dorothy's dog ,Toto, because Toto had eaten up all of the Witches plants.
The Good Witch of the North was trying to help Dorothy to The Wizard of Oz so she could get home to her family and away from the witch.
