"Dragonshy"

A sleeping dragon's smoke is disrupting the skies of Equestria and Twilight Sparkle is tasked with getting it to leave. All of her friends are set to head to the dragon's lair, with the exception of the fearful Fluttershy, who is not used to the rocky terrain, much less a giant dragon. The timid Pegasus must find the resolve necessary when her friends are in danger.
