When I wrote this, there was no particular episode focusing on Scootaloo and her attempts of getting a cutie mark on her own. In this story, like Apple Bloom tried in the series, Scootaloo goes to Twilight for some magical assistance, but not via such direct influence. When a spell goes awry, they struggle to fix it, and Scootaloo learns a valuable lesson.

Edit:Fixed Grammar and Spelling, i think~
