"Who let Appletini in here?" Spike deadpanned, staring at the miniscule pony sitting atop the hoofrest of her chair-throne-thing.
"Ah did, Spike! Ah did!" Applejack squeaked, suddenly shrinking to half her size. Again.
"Huh?" Spike began, "Where'd she go? I swear she was right here a moment ago..."
Meanwhile, Applejack floated away on a dust particle, ready to explore worlds beyond the confines of Equestria.
And maybe find a way to grow back to normal size.
