Book excerpt: How do you keep a crowd of energetic young penguins entertained? Put on a play, perhaps? But will they pay attention through an entire performance? If Tacky’s center stage, they might. Even in his flowing blond wig and little red “skipping shoes,” everyone’s favorite misfit penguin imbues the character of Goldilocks with his own indomitable personality and style. So what if the set is in shambles? This is one performance Mrs. Beakly’s students won’t soon forget.
