Who takes your baby teeth when they fall out? In France, it’s la Petite Souris, the little mouse.
FYI: Many countries have traditions that have rodents rewarding baby tooth loss with loot. In Spanish and Hispanic American cultures when a child loses a tooth it is customary for him or her to place it under the pillow so that Ratoncito Pérez (or Ratón Pérez or "el Ratón de los Dientes" ) will exchange it for a gift. In Italy, the tooth fairy is also often replaced by a small mouse. From parts of Lowland Scotland comes the tradition of the white fairy rat who purchases children's teeth with coins.
