In this funny let's-go-shopping picture book, Mercer Mayer's famous Little Critter is having a ton of trouble with his little sister. When the family goes shopping, his sister pulls groceries off the shelves, finds a way to get lost, and cries when she can't have all the candy in the candy aisle. The day is a disaster -- until Little Critter's mother invents a way to put a smile back on everyone's face.
