Pink Fluffy Unicorns Dancing on Rainbows is a novelty internet song by Andrew Huang that became widely known on YouTube in the early 2010s. Its ultra-cheery melody and repeated lyric made it easy to quote, remix and reuse in meme edits. The sound stayed popular because it is instantly recognizable and creates a strong contrast with almost any visual. Online, it often appears in goofy ahh sounds compilations and brightly edited clips where creators want a sudden, playful mood shift.
