This book tells the story of four characters - two mice (Sniff and Scurry) and two little people (Hem and Haw) - who search for cheese in a maze each day. One day, they arrive to find their cheese has been moved to a new location. Sniff and Scurry quickly adapt to the change, while Hem and Haw struggle to accept it. The story is an allegory for accepting and adapting to change. It teaches that one must regularly monitor their environment for changes, be willing to adapt quickly, and move forward rather than dwelling on the past.
