Santa Claus knows all the children, but the fact that the Christmas Mouse was living in Santa Claus´s house was a secret nobody knew—not even Santa Claus— until now, because the little mouse hid really well. While Santa Claus wraps his gifts, the mouse watches attentively and picks up everything that falls onto the ground: toy cars, marbles, colored ribbons… Later, he gets the gifts ready for little mice around the world and, on December 24th, he travels with Santa Claus—in his special hiding place—to hand out all his gifts. An adorable story about Christmas gifts for big and little mice.
