Chubby always eats, walks, and plays alone—until one day, he meets a masked tree spirit named Little Tree under a giant tree. Their bond sparks laughter, friendship, and the creation of the “Little Tree Defense Squad,” where four children protect their secret green haven. But when humans threaten to destroy the tree, Little Tree must return to the forest. For the first time, Chubby steps forward, determined to find his friend and protect the world they love with his own courage.
