Everybody knows that Grandfather Frog has a big mouth. Of course! It wouldn't be possible to look him straight in the face and not know that he has a big mouth. In fact, about all you see when you look Grandfather Frog full in the face are his great big mouth and two great big goggly eyes. He seems then to be all mouth and eyes. Anyway, that is what Peter Rabbit says. Peter never will forget the first time he saw Grandfather Frog. Peter was very young then. He had run away from home to see the Great World, and in the course of his wanderings he came to the Smiling Pool. Never before had he seen so much water. The most water he had ever seen before was a little puddle in the Lone Little Path. So when Peter, who was only half grown then, hopped out on the bank of the Smiling Pool and saw it dimpling and smiling in the sunshine, he thought it the most wonderful thing he ever had seen. The truth is that in those days Peter was in the habit of thinking everything he saw for the first time the most wonderful thing yet, and as he was continually seeing new things, and as his eyes always nearly popped out of his head whenever he saw something new, it is a wonder that he didn't become pop-eyed.
