Basically, Ford Pines from Gravity Falls discovers MLP and binge watches the entire series in record time. He then creates an AU where the cast of GF and himself are ponies, and Ford is the pupil of Queen Twilight Sparkle. Soos works with Stan at whatever job he's most recently acquired, looking up to him as an older brother figure.
