What are the little people called in Willy Wonka and the Chocolate Factory?

The little people in the lands of Oz are called the Munchkins. They live in the Blue Munchkinland Country of the East. And they were most welcoming to Dorothy and her pet dog Toto. For the landing of Dorothy's farmhouse on top of the Wicked Witch of the East freed the Munchkins from the Witch's wicked rule.
