Lace up your skates, everypony, we're heading to the Kenbucky Roller Derby! After getting rejected from the local roller derby team, Sunny sets out to form her own team. Thanks to self-appointed team manager Pipp and her ClipTrot sleuthing skills, they find the perfect pony to join them: Tracy Tailspin, retired derby legend! And she lives right in Maretime Bay! Tracy agrees to help on one condition: Sunny must complete a super-challenging skating obstacle course. But with her sights set on the Kenbucky Roller Derby, nothing can stand in her way!
