These little Piu Piu birds are meant for office use, where their main duty (due to their magnetic nature) is to hold paperclips. In our house however, these little birds are cute little companions to my children. I’m not really sure how it works (if it’s the movement of the hand or the warmth of the palm), but if you hold these little lovebirds in your hand they begin to sing! Very cute, and I’m actually very glad I got each of my children their own bird, because it’s one of those toys they will always fight over. And if they ever get tired of them? Then I’ll take them to the office! (The birds, not the kids.) Everybody happy!
