(MLP:FiM/Mushishi crossover) Without warning, strange black and white spirals appeared on the flanks of the Cutie Mark Crusaders and their classmates, and the spirals force the foals to stand outside all day long for seemingly no reason. Applejack, Rarity, and Twilight struggle to determine the cause, but come up empty hoofed. However, their salvation comes in the form of a strange stallion with a white mane and green eyes. The stallion calls himself Ginko and claims he’s a mushishi.
