One hot summer's day nine-year-old Sarah goes to the grocery store ... and comes home with an elephant. Sarah's new elephant is not without its challenges, he has trouble fitting through doorways, knocks over everything in sight, is allergic to the neighbor's cat and cowers at the sight of a mouse. But he also has a knack for arranging flowers and keeping Sarah company. And it's because of the elephant that Sarah meets her new next-door neighbor and makes her first real friend. It's because of the elephant that Sarah's mother starts spending more time with her. In fact, despite the destruction, just about everything good that happens is because of the elephant. It turns out that every home, and every nine-year-old girl, DOES need an elephant.
