Meet Fern! She’s a smart, creative unicorn who prefers building robots and coding software to jumping through shimmering rainbows and splashing in majestic waterfalls. Even though Fern is a good friend and always willing to help others, the other unicorns tease her and call her a nerdycorn. One day, Fern has had enough and decides to stop fixing her friends’ broken things. But then the confetti machine, the rainbow synthesizer, the starlight bedazzler all go haywire during the biggest Sparkle Dance Party of the year! Fern can certainly fix them...but will she?
