Pinkfong's Baby Shark became a global children's phenomenon after its bright dance video spread on YouTube in 2016, turning a simple campfire-style singalong into one of the most-viewed videos ever made. Its short, repetitive hook made it easy for children and adults to remember, parody and share, and the song soon appeared in classrooms, birthday parties and countless short-form videos. The five-second opening remains popular because it is instantly recognised even without the full song.
