Rainbow Dash is lonely. It isn't long after the death of her best friend, the energetic Pinkie Pie, and she decides to tamper with the laws of nature and take things into her own hooves. Her quest: to create her own Pinkie Pie, one that won't leave her behind. But her experiments don't quite go as planned, and she is left with an oddly coloured, robotic foal. But can she just cast it aside? Can she just pass it off as a failure? Can she ignore it when it looks at her with those eyes? Those scared, green eyes...
