While Ditzy Doo and her sister Daring Do go on an epic quest and Rainbow Dash struggles to keep them both from killing one another, Ditzy's very own daughter Dinky embarks on a secret adventure of her own. Inducted as an honorary member of the Cutie Mark Crusaders, Dinky Doo finds herself tagging along with Sweetie Belle, Apple Bloom, and Scootaloo as the four fillies set out to take back Mr. and Mrs. Cake's foalnapped twins. Their journey carries them across land, sea, and even parts unknown as they seek out their hidden talents in this precocious act of heroism. Not long into the quest, however, Dinky learns that doing the "honorary" thing means more than the title itself, and what started as a daring Crusade swiftly turns into a voyage of self-discovery that she had never asked for.
