One day, an enigmatic pony named Burke arrives in Ponyville, looking for some pony, or some ponies, to carry out his evil plan. He happens across the Cutie Mark Crusaders, and promises them their cutie marks in return for their assistance in blowing up a bomb that has long been hidden underneath the town's soil. Hijinks ensue.

Note: Not related to Fallout Equestria, and not a full crossover with Fallout either. Rated T for comedic violence.
