Once upon a time there lived a farmer. He was very fair, so all the little children in the village called him “sudu mama”. This farmer reared many cows. One of the cows gave birth to a black calf. When the calf grew older,it became very playful. One day as the calf was running about, it fell into a field full of mud. It could not get out and little by little it began to sink in the mud….
