New York Times bestselling author/artist tells the story of two best friends who are opposites in almost every way!

Big is an elephant, Little is a mouse. Big enjoys soft music, warm weather, and small bites of savory foods. But Little prefers a loud drum jam, icy skiing weather, and mass quantities of sweets! Can two who are so different be best friends? This charming, rhyming concept book about opposites reminds us that in the end, best friends can be different as night and day—and they don't need to change for anyone!
