Grandfather Frog in "Striped Chipmunk Cuts The String"

"Why, Grandfather Frog, what under the sun are you doing here?" he shouted.
When Striped Chipmunk let go of the string, Grandfather Frog promptly drew his feet back under the old board, but when he heard Striped Chipmunk's voice, he slowly and painfully crawled out. He told how he had been caught and tied by Farmer Brown's boy and finally dropped near the old board. He told how terribly frightened he was, and how sore his legs were. Striped Chipmunk didn't wait for him to finish. In a flash he was at work with his sharp teeth and had cut the cruel string before Grandfather Frog had finished his story.
