The Field Mice who live in the magical Land of Oz are a very unique race of rodents who can talk and live on the outskirts between the Munchkin Country border and the Emerald City. The mice all live very close to the field of deadly Poppies and mostly stay underground. They are all ruled by a Mouse Queen. The mice appear in L. Frank Baum's first Oz book titled The Wonderful Wizard of Oz published in 1900. They appear in the ninth chapter of the book titled The Queen of the Field Mice. Despite being a rather important part of the original story, who help save the lives of Dorothy Gale, the Field Mice of Oz have yet to make an appearance in the Oz movies.
