Fumofumo san - long arms stuffed animals

Have you ever heard of fumofumo san? They are a line of stuffed animals designed by the Japanese company Shinada. These cute stuffed animals have characteristically long arms that you will never forget about. At first, I thought these out of proportion arms have no functional use other than just a design form. But very soon, I discovered that you can easily wrap the soft arm around your neck to keep yourself warm at night. Is this serendipity? I really want to know too!
