En el país de Lindabrina y Ratón Pérez

When Ana's tooth begins to move for the first time, her parents place a small wooden door in the corridor of her house with a mouse drawn on it: it is the door of Ratón Pérez, which opens onto a world of wonders that only children like her can enter. It is there that she meets Mr. Mouse, always busy with his bag full of teeth. And he is not the only extraordinary being there: the fairy Lindabrina, a kind creature, rules that magical and precious world, made up of children's drawings, which come to life there. In this world, things also break down and get damaged, but Ana and her friends fix it very easily with more drawings. And so, again and again, harmony reigns in the country of Lindabrina, everyone is happy and having fun, until some strange and evil beings invade the country and Ratón Pérez disappears.
