Dreams.

In the Southern islands there is a duck named P'eng. On rainy ducks he is known to quack. The quack of P'eng reverberates through the ocean, creating large ripples that continue across the water until they meet the land. P'eng does not know why he quacks, nor does he realise the consequences. It just so happens that when the storm clouds roll across the sky, and the rain begins to fall, P'eng suddenly feels like singing.
