Wanneer het jonge meisje Lucía haar tand verliest, vertelt haar moeder dat The Hairy Tooth Fairy deze 's nachts komt ophalen en een beetje geld in de plaats legt. Een muis in het huis heeft dit gezien en vertelt het verhaal door. Zo komt dit ter ore van Perez, The Hairy Tooth Fairy. Normaal gezien gaat Perez de tanden verzamelen, samen met de andere muizen bewerken ze de tanden tot ze tot glimmende parels omgevormd zijn. In ruil krijgen ze van de juwelierMorientes het gewicht terug in goud. Maar deze keer loopt het niet van een leien dakje...
Nee, helaas is El ratón Pérez nog niet beschikbaar op Netflix in Nederland.
