One day, another snake came near to the lake, and saw frogs riding on the back of the old snake, he questioned the old snake, why do you carry all these frogs, how dare, they are riding on your back? The old snake replied, as long as I eat these frogs, I have no problem for food. The King frog asked the old snake as to what he was talking with the other serpent? The old snake suddenly changed the topic, and said to the  King frog, that it was nothing.
