Down at the pond on a Tuesday evening around 8:00, lily pads mysteriously begin to function as flying carpets, lifting frogs gently from the water's surface and carrying them into a nearby town. A horde of benign airborne frogs descends upon the town's unsuspecting, apparently oblivious, human residents who continue with their mundane routines undisturbed -- eating a late-night snack, falling asleep in front of the television set, etc. Whatever the magic, it apparently fades away with the rising sun and the frogs hop back to their watery home, leaving the townspeople to puzzle over an inexplicable infestation of lily pads on city streets. A nearly wordless book invites readers to supply the details about an unusual occurrence wryly depicted with watercolor paintings which succeed in a perfect blend of realism and fantasy. (Ages 3-8)
