Grandfather Frog in "Grandfather Frog's Big Mouth Gets Him In Trouble"

Grandfather Frog has a great big mouth. You know that. Everybody does. His friends of the Smiling Pool, the Laughing Brook, and the Green Meadows have teased Grandfather Frog a great deal about the size of his mouth, but he hasn't minded in the least, not the very least. You see, he learned a long time ago that a big mouth is very handy for catching foolish green flies, especially when two happen to come along together. So he is rather proud of his big mouth, just as he is of his goggly eyes.
