Ratoncito Pérez

The Ratoncito Pérez or Ratón Pérez (Pérez Mouse in English) is a figure popular in Spanish and Hispanic American cultures, similar to the tooth fairy, originating in Madrid in 1894. As is traditional in some English-speaking countries, when a child loses a tooth it is customary for him or her to place it under the pillow, so that Ratoncito Pérez will exchange it for a gift. The tradition is almost universal in Spanish cultures, but takes different forms in different areas. He is known as "Ratoncito Pérez" in Spanish speaking countries, with the exception of some regions of Mexico, Peru and Chile, where he is called "el Ratón de los Dientes" (The Tooth Mouse), and in Argentina, Venezuela, Uruguay and Colombia, he is known simply as "El Ratón Pérez".
