On the day Mom goes shopping with her young daughter, baby Harry, and Wilf the Wonderdog, she starts by making her usual grocery list. But with Allan Ahlberg at the helm, what begins as a mundane shopping trip can quickly become just a little unusual. With the help of whimsically detailed illustrations by André Amstutz, this persistent family treks through a blizzard and under the desert sun, into a jungle of tropical beasts, and even across the sea. But what will they find at the end of their journey?
