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! But they'll need more skaters if they want to win the Kenbucky Derby, the toughest championship in Equestria. Sunny holds tryouts for all the other creatures who are either too mean, too scary, too uncoordinated, or… the Pegasnails, who are all heart but no limbs. Can the newly formed Maretime Bay Brawlers battle their way through the competition to take home the trophy? Or has Sunny just signed her friends up for rink rash and disappointment?
