Paddy The Beaver in "Paddy Plans A Pond"

And all the time the Laughing Brook was having harder and harder work to run. Its merry laugh grew less merry and finally almost stopped, because, you see, the water could not get through between all those poles and sticks fast enough. It was just about that time that the little people of the Smiling Pool decided that it was time to see just what Paddy was doing, and they started up the Laughing Brook, leaving only Grandfather Frog and the tadpoles in the Smiling Pool, which for a little while would smile no more.
