It's Twilight's first day at Unicorn University, and she's nervous from the tip of her sparkly horn to the end of her shimmery tail. And when Twilight gets nervous, sometimes she loses control of her magic power, and turns invisible by mistake! But she can't help her feelings. What if the other unicorns laugh at her power? What if she doesn't make any friends?

To make matters worse, the first day of school is also class picture day. With everything going on, Twilight keeps accidentally flickering out of sight, until finally she turns invisible...and realizes she can't turn herself back! Can Twilight reappear in time for the class picture?
