The Wizard of Oz Part 2

Ruby thinks that every movie has a sequel.  She hasn't actually seen The Wizard of Oz, but she loves the pictures she's seen of Dorothy and Toto and I've told her what I can remember of the story.  Today, she found a green stone and I heard her saying something about the Emerald City.  When I asked her what she was doing, she went on to tell me her elaborate story of The Wizard of Oz Part 2.  Basically, the Wizard had given Dorothy this green stone and whenever she holds it up she is able to see a green door through it.  Then she can just walk through the door back to the Emerald City and get as many emeralds as she wants.  I don't think Ruby will have any trouble with creative writing!!
