Small Horn, Harmony Trebleheart, Vast Data, and Crankshaft. Four ponies that were once humans.
Well, they were always ponies.
Well, in a human body.
Well, you know! It's confusing!
A call came out from a farm in the US that only ponies could get.
With Discord chasing them, all three need to get to that farm before Discord defeats than and mankind. (But why should ponies give two poops about mankind?)
The sequel of kwr2k13's Small Horn. I would suggest reading that one first, or else none of this will make sense.
A collab fic done with (cast):
kwr2k13 = Small Horn
Me! (Sparkler Hooves) = Harmony Trebleheart
BLT185 = Crankshaft
Vast Data = Vast Data
