Wrens are born to sing! So, what do you do when you are a wren who can only squeak? Poor little Wren Three had this very problem. Though Mamma Wren and her other siblings, Wren One and Wren Two, loved her very much, Wren Three could not sing like they could. One day, Wren Three makes a new friend: Picco, the piccolo, and they soon share each other's talents. Picco flew with Wren Three on her back, while Wren Three listened to Picco's beautiful music. All is well until Picco has a bad fall and can no long play music until he is healed. Wren Three eventually finds her singing voice as she persistently tries to serenade Picco back to health.
