Little Sprite Gray Bean is an ugly yet kind-hearted little imp who is determined to shed his impish shadow and become a true human. With the help of the powerful but mischievous Bajie and the Great Sage, he drives away the big-mouthed monster that plagued the mortal world in the undersea Dragon Palace; he kindly tries to draw eyes for a dragon but ends up drawing them crooked; he returns the red fish scales to their rightful owner; and at Maitreya Buddha's place, he masters the skill of an iron butt, bravely attempting to mend the sky—despite enduring countless grievances, Little Sprite Gray Bean still strives to become a good person.
