The Wizard of Oz is one of the many franchises featured in LEGO Dimensions. It is based on the classic 1939 film, which is in turn based on a book.
When a tornado rips through Kansas, Dorothy and her dog, Toto, are whisked away in their house to the magical land of Oz. They follow the Yellow Brick Road toward the Emerald City to meet the Wizard, and en route they meet a Scarecrow that needs a brain, a Tin Man missing a heart, and a Cowardly Lion who wants courage. The wizard asks the group to bring him the broom of the Wicked Witch of the West to earn his help.
