Travel through time following a charming little mouse called Minim, who happens to love cheese and music. With great courage, he braves a cold Venetian winter night to visit an orphanage. His mission is to replace the tooth fairy by leaving a little gift under the pillow of each child. Little does he know that this task is fraught with danger. A tomcat is lurking about in the building, always on the lookout for his next meal. Luckily, it's also home to the great composer Antonio Vivaldi, whose music will prove irresistible!
