Informant: Valentina Williamson. 11 years old. Born and raised in Mexico City. My little sister,

Informant: “Whenever a tooth fell out, I would put it under my pillow and the “Raton Pérez” (Mouse Perez) would take it away and leave me money.”

Collector: “When did you first hear about the Ratón Perez”

Informant: “I guess I heard it from my parents. When my first tooth fell out they told me to place it under the pillow as and the ratón would exchange it for money.”

Collector: “Do you know why the ratón took teeth?”

Informant: “My parents told me he wanted my teeth because he collects teeth from all the children around the world. Also, all my friends had the same experience. We all believed in the ratón and would show off the money he gave us.”

Me: “Why did you believe in the Raton Pérez and not the tooth fairy.”

Informant: “If my tooth fell out in Mexico it was the Raton Perez’s job. If I was in the U.S. it was the Tooth Fairy’s job. Like once my tooth fell out when I was in New York and I believed the tooth fairy took it. It was all about where I was. HA HA!  I even thought they would meet up and compare their tooth collections.”

Thoughts: The Raton Perez and Tooth Fairy are classic folklore parents tell their children. What interested me the most from my sister’s performance is that she believed it was locational rather than sticking to one belief. I also know that in Spain they call it “Ratoncito Pérez” or “Little Mouse Pérez.”
