The kids are having a yard sale, getting rid of old toys, books and clothes. Kioko shows up holding a prized possession-a music box from Switzerland. By accident, Ben includes the music box in a cardboard box of yard sale items-and the music box is sold! Kioko is sad and Ben wants to make things right, so he and Barney travel to Switzerland in search of a replacement gift. While there, they sample Swiss food, customs and games-but no music box! Luckily when Ben returns the music box is returned!
