Grandfather Frog in "The Dear Old Smiling Pool Once More"

"Chugarum!" cried Grandfather Frog, and it was the loudest, gladdest chugarum that the Smiling Pool ever had heard. "Chugarum!" he cried again, and with a great leap he dived with a splash into the dear old Smiling Pool, which smiled more than ever.
And never again has Grandfather Frog tried to see the Great World. He is quite content to leave it to those who like to dwell there. And since his own wonderful adventures, he has been ready to believe anything he is told about what happens there.
