A dragon has taken up residence in the mountains near Ponyville, and its smoke breath is drifting over all of Equestria. Princess Celestia has sent the Mane 6 to convince it to leave...but when they arrive at its cave, they find a slightly different kind of dragon than what they were expecting. They find a Magic Dragon. With a chihuahua.

(Alternate "Dragonshy" featuring Piff the Magic Dragon. Maybe you know him, he’s a Magic Dragon. One-off I-don't-even-know-what-or-why. Crossover with real life, I guess? #VOTEPIFF)
