Paddy The Beaver in "Farmer Brown's Boy Grows Curious"

Now it happened that the very day before Paddy the Beaver decided that his pond was big enough, and so allowed the water to run in the Laughing Brook once more, Farmer Brown's boy took it into his head to go fishing in the Smiling Pool. Just as usual he went whistling down across the Green Meadows. Somehow, when he goes fishing, he always feels like whistling. Grandfather Frog heard him coming and dived into the little bit of water remaining in the Smiling Pool and stirred up the mud at the bottom so that Farmer Brown's boy shouldn't see him.
