In Dust Mountain, the life philosophy of "Potato", the mole spirit, is buried in the soil. As the self-proclaimed "Chief Tunnel Officer," his greatest happiness is the scent of earth that lingers on his nose when he swings an old shovel. His lifelong dream is to win the small fine steel shovel that the king gives as the first prize by virtue of his diligent tunnel digging skills.
Completely opposite to him is the sparrow spirit's best friend "Cui Yu" who yearns for the world outside the mountains. One is down-to-earth, the other is in the clouds. They are the most unique scenery in each other's eyes.
However, under the seemingly peaceful daily life of the mountain forest, there is an undercurrent surging. The Queen's mysterious and serious illness has shrouded the entire Dust Mountain in an invisible depression, adding a touch of anxiety to the King's majesty. At this moment, the old shovel that Tudou relied on for a living broke, and his little dream seemed to be shattered.
When an individual's trivial wishes intersect with the imminent crisis of the entire group, how will this little mole spirit, who only knows how to bury his head in digging holes, face the challenges that are coming? What new meaning will be given to the land he cherishes and the "road" he is obsessed with? This is a warm fable about persistence, growth and responsibility.
