Buster, Wink, and Wiggle met him by the pond.
"All safe, Grand-daddy?" they cried.
"Sure," grinned Grand-daddy. "They are harmless folk. Have you seen a gray paper balloon dangling from the bushes, kiddies?"
"I have," cried Wink. "Uncle said hornets lived in it and they were real fighters."
"I'll fight 'em, then. I want that nest for medicine. Trot ahead and show it to me."
"Hi! hi! Dr. Whiskers!" came a cry from the Lake.
Grand-daddy ran to the water's edge. There sat Grandpa Bull Frog groaning miserably.
"Hello! a fish hook!" exclaimed Dr. Whiskers. "Let's see if I can extract it."
He took a sharp instrument from his bag.
"I'll be as careful as possible, Grandpa Bull Frog, but it is bound to hurt you considerable," he explained. "Now open your mouth wide."
