Twilight discovers a spell that could split an object into different objects. Deciding to test it out, the spell backfires and splits the Alicorn princess into two different ponies. One is a rough and tough pegasus that goes by the name Twilight Moon, the other is a patient and elegant unicorn with the name Sparkling Glow. Without knowing how to reverse the spell, Twilight and Sparkle must find a way to combine themselves together, or learn how to live their new and weird lives

Reason why it's cancelled.
