Lyra Heartstrings is a teenage girl who likes to draw and wonder into her little own world. One day, after drawing her own world, full of colorful magical ponies, she wakes up, not expecting the drawing to come true. She and her friends are ponies, and Lyra finally gets what she wants, her own world.

But is this really what she wants? Being a pony, not being able to walk on two feet, but using all fours and instead of hands a horn?
