It starts with a bored Dorothy playing fetch with Toto. Suddenly a tornado strikes and whisks her away to Oz. There, Dorothy and Toto meet the Scarecrow and the Tin Woodsman. When the group arrives at the Emerald City, there is a parade being thrown. Dorothy and her friends join the parade and end up arriving at the Wizard of Oz's castle. They meet the Wizard and he performs tricks for them. One of the eggs he creates doesn't hatch and, instead, it grows to a huge size. After much trouble, the egg hatches to reveal a baby chick. The short ends with the characters singing "Rockabye Baby" to the chick and its mother.
Though the short is only vaguely based on the source novel, it used the idea of Dorothy suffering from Small Town Boredom years before the more iconic MGM film of the same name did. It's also the first medium to depict Kansas in Deliberately Monochrome but Oz in full-colour, taking a cue from L. Frank Baum describing Kansas as a "gray" place, and Oz as boasting several colors. The MGM film took several aspects from this cartoon and used it.
The Wizard of Oz is also one of the first animated works to be made in color and one of the first to have a complete soundtrack. The former led to legal issues, however. Due to legal troubles with the Technicolor Corporation (which at the time only allowed Disney to use its 3-strip process), the short was never distributed. Due to this, it hasn't been as properly preserved as other shorts from the period. The first commercial release was in 1985 and it has since been rereleased several times in varying qualities.
This short provides examples of:
- Adaptational Badass: The Wizard is an actual wizard in this short.
- Adaptation Dye-Job: Dorothy wears a blue dress, not her normal gingham dress.
- Adapted Out: Most characters are not present. Aunt Em and Uncle Henry, the Munchkins, the Cowardly Lion, and the witches don't appear.
- Deliberately Monochrome: The first few seconds of the short was presented in black and white. But when Dorothy and Toto land in Oz, the short then transitions to color.
- Gainax Ending: The short ends with the giant egg exploding to reveal a baby chick. Thus Dorothy and her friends sing Rockabye Baby to the chick.
- Mime and Music-Only Cartoon: The short virtually has no dialog, save for Dorothy shouting Toto's name at the beginning.
- Mix-and-Match Critters: During the Wizard's magic show, he uses his wand to enchant a bunch of eggs. Which hatch into various creatures with the heads of different animals, and the bodies of chickens.
- Monochrome to Color: Once Dorothy and Toto fall straight down to Oz, the short then changes from black and white to color.
- No Ending: Due to the series never being green-lit, Dorothy is still in Oz.
- Spared by the Adaptation: Dorothy never kills the Wicked Witches.
- Visual Pun: While crossing Oz, the gang sees a bunch of lovey-dovey birds and bees. The bees go into a flower together and a few seconds later pop out a bunch of their offspring.
- Wizard Beard: The self-proclaimed Wizard has one.
