Grandfather Frog in "Old Mr. Toad Visits Grandfather Frog"

"Oh," replied old Mr. Toad, "I'm not afraid. Farmer Brown's boy is a friend of mine. I help him in his garden. How to make friends is one of the things the Great World has taught me."
"Chugarum!" said Grandfather Frog. "I'd have you to know that—"
But what it was that he was to know old Mr. Toad never found out, for just then Grandfather Frog caught sight of Farmer Brown's boy and without waiting even to say good-by he dived into the Smiling Pool.
