This story is a sequel to Mission: Improbable

A few weeks after the Spy returned from his extended stay in Equestria, the Medic found that he needed to have a few of those so-called "ponies" to... study. But with robots still attacking Mann Co., how can he find the time to acquire such a specimen?

By sending a scout ahead, of course.

Twilight Sparkle's latest assignment is to make a new type of Mountain Dew, the popular magic-boosting drink for unicorns. Twilight's experiment works a bit TOO well, and two of her friends are accidentally turned into unicorns! Can they get back to normal, before things get out of hoof?

Strange discoveries. Mysterious twitching. The curious feeling of being watched. And a sudden urge to sing. Something's happening to Applejack, and no matter how often she laughs, this is no laughing matter!
