Just as Dorothy has woken up from the storm, she is in the "Deadly Desert" with the Chicken, Bellina. Then the chicken says, "There goes the water." The camera then goes to a wide view so you can see the water disappearing. Then, when the camera goes back to Dorothy, you can see water to the right behind her head! I wonder where that came from!

When Dorothy first meets Tik Tok, he pledges to be her obedient servant, and bows while lifting his hat. If you watch during the bow, you can see the bobbing head of the puppeteer who's working him.
During the emerald city parade at the end of the film, there is a tiny blooper. At the beginning of the scene, when the oz citizens enter the mirrored ball room, the camera pans out. If you watch closely, the camera man catches himself in a mirrored pillar on the right side of the screen. He's dressed in white, but he's only there for a second.
