I used to believe in the Raton Perez (a mouse who would take my fallen tooth and place money under my pillow). I was so convinced that he existed that I told my sister I saw him wearing pants, a vest and running around trying to find a hole to leave. Unfortunately there were no holes, so we provided a burial since he obviously must have died since he was unable to return home. We never did find his body ;o)
