Now the Biggest Frog swallowed a great deal of air, filled the sacs on each side of his neck with it, opened his big mouth, and sang croakily, "Frogs! Frogs! Frogs! Frogs! Frogs! Frogs! Frogs! Frogs!" And all the others sang, "Frogs! Frogs! Frogs!" as long as he. The Gulls heard it, and the Muskrats heard it, and all were happy because spring had come.
