Everypony must undergo a trial upon turning 16. It seems simple enough, go from one side of the everfree forest to the other, but many ponies don't succeed for reasons unknown. Scootaloo has finally turned 16 and must face the trials, she has been training with Rainbow Dash for almost a month and is ready for the journey. Her friends and even the class dunces have completed their trials, so it should be easy enough for the mirror mare of the great Rainbow Dash. However, the everfree forest has been changing recently without any notice from the residents of Ponyville. Will Scootaloo make it through the everfree forest and back, or will she end up like so many others?
