A crate of newly made toy bears is unpacked in a department store and, when the humans are asleep, the toys come to life and embark on nocturnal adventures. They explore the store, mingle with other animated playthings, and take part in rescues, games, and window displays. Episodes carry them beyond the shop to a farm, a nursery, the kitchen, a cleaner’s, and even a sea voyage, while visits from children such as Sally and Bob frame several scenes. Individual bears develop distinct quirks through naming, inventive play, and small mischiefs, and the book moves through celebrations, seasonal happenings, and dreamlike moments.
