Did you know the Tooth Fairy is a mouse? In Spain and across Latin America, when a child loses their first tooth, it is not a fairy who comes - it is the most dapper, clever, kind-hearted little mouse in all of Madrid.

His name is Ratoncito Pérez.

He lives with his family in a cozy cookie box beneath the streets of Madrid. Every night, while his family sleeps, he sets off through the secret underground tunnels of the city - collecting lost teeth and leaving gifts behind for sleeping children. One night, a young king named Bubi loses his very first tooth. When Ratoncito Pérez arrives to collect it, little Bubi is waiting - and the adventure that follows will change him forever. Together, the small king and the dapper mouse travel through the tunnels of Madrid, meet the warmhearted Pérez family, sneak past an enormous sleeping cat, and visit a poor little boy named Giles - whose cold and humble room teaches Bubi something no palace lesson ever could.

A beautifully illustrated fairy tale about compassion, friendship, and the magic of the night - based on the beloved classic Spanish story by Luis Coloma, written for King Alfonso XIII of Spain in 1894.

A timeless tale, lovingly retold and illustrated for a new generation of dreamers.
