Herbie is a little hedgehog who is perfectly happy at home with his mother. But one day Mommy tells Herbie that it's time to go exploring—all by himself! Herbie is so not sure, but ready or not, a westerly wind sweeps Herbie into the wide world...and Herbie's Big Adventure begins! Little Herbie finds that he's braver than he thinks and even makes a friend before coming safely back home to Mommy.
