A wordless picture book details what happens at a local fair once the humans go home for the night. It turns out the woodland animals have been biding their time and stream in as soon as the coast is clear. Some work the fair, selling tickets, running games and rides, making food; others enjoy all the fair has to offer, dizzy and dazzled by the lights, the games, and, especially, the rides. Scenes that give a sense of nighttime mystery alternate with the bright, bouncing energy of the fair, but all good things come to an end. There’s a close call when a guard returns just before dawn, but by then the animals have finished cleaning up (most of) the mess and evidence of their escapades. Superb watercolor, gouache, and colored pencil illustrations tell the story in panel and full-page images full of humor (long-legged deer dangling from seats on the swing carousel; a goldfish prize for a fox at the ring toss) and sometimes poignancy (the tender, surprising fate of the goldfish at story’s end). (Ages 3-8)
