Sunset is beat after a long day at school. After a day of stress, Sunset just wants to have a bit of fun after school. Luckily for her, her friend Pinkie Pie is a master of fun. And what's more fun than visiting a carnival? With rides and fried foods and fun in store for the evening, Pinkie Pie plans to help Sunset have a night she'll never forget.

Of course, if Pinkie's being super-duper honest with herself, the carnival might provide the opportunity she needs to get something off her chest. A secret that makes her feel like she'll explode if she doesn't say it soon. But how do you tell your friend something this big when you know it might change everything?
