What do your toys do when your back is turned? Mischief — and a bit of wish fulfillment — are in play when a ringleader teddy bear throws a very memorable party.

Have you ever wondered what stuffed animals do while their companion humans are at school? What if a teddy bear invited all his stuffed animal friends over? Imagine the wild party that might ensue, complete with jumping (a little too hard) on the bed, coloring on the walls, dressing up in Mom’s clothes, having a bubble-bath sliding contest in the hall, sledding down a “cushion mountain” on a cookie tray. . . . As adorable as it is raucous, Jancee Dunn’s whimsical tale of freedom and fun comes to vibrant life in Scott Nash’s colorful illustrations.
