Answer and explanation:
The Witch of the North is a good witch in the Oz stories by L. Frank Baum. She has a magic hat which, when balanced upon her nose, gives her the power of divination. She can also teleport herself, transform things into completely different objects, or even animals and people, and cast a protective spell. Even though she is not as powerful as other witches, she still helps Dorothy by kissing her on the forehead. That kiss works as a protection from harm. It is the reason why Dorothy is not attacked by the Winged Monkeys and the Wicked Witch of the West.
