Review：This is a picture book which appeals to a wide age range and its possibilities are endless. For those of you unfamiliar with this treasure, we start before the title page as we see frogs, peacefully at first on their lily pads and then slowly levitating. After the title page, we join a pond turtle as he looks up in amazement. The book proper begins at sundown where text says: "Tuesday evening, around eight." The frogs start flying solemnly at first and then with increasing glee as they fly through the town, entering houses, startling dogs and one man enjoying a midnight snack. The time is the only text given as the night continues. As dawn approaches, the pads and the frogs they bear fly lower and lower until the pads fall to earth and the frogs leap back to their pond, leaving the villagers to wonder at the lily pads left behind. The last page gives the time as "Next Tuesday, seven fifty-eight p.m." and we see shadows of flying pigs on a barn door.
