The sound comes from Scooby Doo Pa Pa, a dembow track by Dominican artist DJ Kass that became a global dance challenge after clips of people dancing to its hook spread across Instagram and later TikTok in 2018. The song's simple chant and driving beat made the routine easy to copy, and creators kept remixing it for comedy, dance and party videos long after the original challenge faded. Its short, high-energy hook still works because it is instantly recognisable and immediately sets a playful, dance-ready mood.
