The bare bottoms of Mother Holle's munchkins were shown.

I feel compelled to mention that the father in this movie is portrayed as an alcoholic, named Mr. Bottle. It went completely over my head as a kid but watching it recently I was a little taken back by it.

One of the frightening scenes that happen in the movie is when Mary-Lou (counterpart of Almira Gulch and Wicked Witch of the West) gets covered in pitch as her "Just Reward".
