Once upon a time, in a corner of the world, there was a place called Happy Valley. Here, the mountains were clear and the waters beautiful, the weather was favorable, food was plentiful, and the people lived in peace and contentment. What protected this land was a magical singing harp housed in a beautiful castle atop the mountain. One day, the evil giant Willie invaded Happy Valley and stole the singing harp. From then on, gloom shrouded the valley, disasters struck one after another, and the once-happy valley turned into a barren land filled with sorrow. Living in the valley were three farmers: Mickey Mouse, Donald Duck, and Goofy, who had reached the brink of starvation. In order to trade for food, Mickey reluctantly sold his beloved calf, only to receive three magic beans said to possess miraculous powers.
