This was in the SD version, I am not sure if the HD on my laptop is different. I am currently re-downloading it in HD To double check on my computer.
You can find the new Derpy after the break.
UPDATE: Both versions of the episode have been modified.
UPDATE 2: As a reminder, The Friendship Express DVD is untouched, Derpy is still Derpy (At least in the ones we got, which are pretty much the same as far as we know)
