One day, after the eggs were all laid and were growing finely (for Frogs' eggs grow until the Tadpoles are ready to eat their way out), the Green Brown Frog sat alone on the bank of the pond and the Biggest Frog's Sister came to her. She had a queer smile around the corners of her mouth. Frogs have excellent mouths for smiling, but it takes a very broad smile to go way across, so when they smile a little it is only at the corners. "How are your eggs growing?" she asked.
