Following "The Yellow Bucket," which gently portrayed the feelings of a baby fox yearning for a yellow bucket and was loved by children, the third volume of the Baby Fox series, which emotionally portrays the feelings of children, has been published, completing the four-volume series.
It is a fairy tale written in a series format with different stories so that it can be read separately or together.

This book is a story about a baby fox, a baby rabbit, and a baby bear, all with pure hearts like children.
A baby fox who loves to watch a paper airplane fly away, saying that a paper airplane that doesn't fly in the sky is as good as dead; a baby fox who practices crossing the suspension bridge little by little every day to meet a female baby fox on the other side; a bear and a rabbit who try to persuade the baby fox to go meet her friends on the other side of the bridge when she's a little older.
After meeting a baby fox girl and having fun playing with her, the baby fox returns to his friends with an irreplaceable treasure in his heart.

The author demonstrates through his work that children's treasures are not mere toys, but living, breathing friends who speak to them and have life.
Even though things may break or disappear, the time spent with treasures will remain in our hearts forever.
Just as the author says that each time a child loses a treasure, it may be taking a step closer to the adult world, the baby fox will also become an adult someday, but it will never forget the time it played with rabbits and bears in the forest.

While writing "Shaking Bridge, Shaking Bridge," the author is said to have personally searched for a shaking bridge that could serve as a background with the artist in order to capture the feeling of a shaking bridge.
This is not something written only with the head, but rather something written with the heart and through direct experience.
So, the feelings of the baby fox, who, despite being afraid, crosses the planks one by one to meet the baby fox on the other side of the bridge, are vividly portrayed.
The baby fox's expression, simply expressed in pastel tones and ink, harmonizes well with the rhythmically written text.
