Nimmie Amee is the Munchkin girl whom the Tin Woodman once loved in The Wonderful Wizard of Oz. She was not named until The Tin Woodman of Oz, as Nick Chopper never went to find her after the Wizard gave him a "kind" but not a "loving" heart, until that novel's protagonist, Woot the Wanderer, encouraged him to do so.
In The Wonderful Wizard of Oz, the Tin Woodman tells Dorothy Gale and the Scarecrow that the girl was a servant for an old woman who did not wish her to marry, and so sought the aid of the Wicked Witch of the East to place a spell on him that caused him to cut himself up with his axe while carrying on his livelihood. In The Tin Woodman of Oz, this was retconned, and in Nick's new telling, she was directly enslaved by the Witch herself.
Nimmie Amee was aware of the spell, which occurred gradually, and was not bothered by his condition and still wished to marry him, but he lost interest when he lost his heart (In Wizard, he lost his heart after his head; in Tin Woodman, he lost his head last and the Witch ran around with it in her arms). Soon a soldier named Captain Fyter also wooed the girl, and the Witch dealt him the same blow, and he sought help from the same tin smith, Ku-Klip. Fyter's head and parts of Nick and his body were incorporated into Chopfyt, a new person, through the use of magic glue found in the Witch's house. Ku-Klip was unable to find one arm, so he fashioned one out of tin. In this way, Chopfyt reminded her of both the men she loved, and she married him, and Baum presented them as a happy couple at the end of the novel, although Princess Ozma forbade Ku-Klip from ever doing such a thing again.
