This story is NSFW and contains futanari. BluePrint is a blue unicorn that travels around Equestria with his best friend, SketchPad, a brown unicorn. During their time at home, BluePrint likes to experiment and create things in his laboratory built underneath their home set atop large mountain called Mt. Grandlin in the Everfree Forest. While working on mixing potions one day, BluePrint creates a transformation potion and plans to use it on SketchPad and a visiting friend, although the results of his experiment turn out much different than he could have ever imagined.
