Grandfather Frog in "Longlegs Visits The Smiling Pool"

Longlegs the Blue Heron watched Billy Mink and Little Joe Otter disappear down the Laughing Brook. As long as they were in sight, he sat without moving, his head drawn down between his shoulders just as if he had nothing more important to think about than a morning nap. But if you had been near enough to have seen his keen eyes, you would never have suspected him of even thinking of a nap. Just as soon as he felt sure that the two little brown-coated scamps were out of sight, he stretched his long neck up until he was almost twice as tall as he had been a minute before.
