Knowing that the dead witch's ruby slippers contain magic, Glinda, the Good Witch of the North, through her powers, has them placed on Dorothy's feet before the dead witch's sister, the Wicked Witch of the West, can retrieve them. The house comes to rest in Munchkinland, a colorful section of the Land of Oz inhabited by little people, and lands on top of the Wicked Witch of the East. When she sees Miss Gulch, traveling in mid-air on her bicycle, transform into a witch on a broomstick, Dorothy averts her eyes.

When she revives, she sees through the window that the house has risen up inside the cyclone. Inside her room, Dorothy is hit on the head by a window and knocked unconscious. Dorothy rushes home greatly concerned, but a cyclone's approach causes her difficulty, and by the time she gets to the farm, Auntie Em, Uncle Henry and the three farmhands have entered the storm cellar. They come to the wagon of the egotistical, but kindly Professor Marvel, a fortune-teller and balloonist, who tricks Dorothy into believing that her aunt has had an attack because she ran away. Realizing that Miss Gulch will come back, Dorothy runs away with Toto. However, as Miss Gulch rides away on her bicycle with Toto in her basket, the dog escapes and returns home.

When Almira Gulch, who owns half the county, brings a sheriff's order to take Dorothy's little dog Toto away to have the dog destroyed, because Toto bit Miss Gulch's leg, Auntie Em and Uncle Henry refuse to go against the law, and they give the dog to Miss Gulch. Dorothy Gale, a Kansas farm girl, lives with her Auntie Em and Uncle Henry.
