Baby Shark began as a traditional children's camp song before South Korean company Pinkfong released its dance version on YouTube in 2016. That video spread worldwide, topping charts, spawning remixes, challenges and translations including this Japanese version, titled in katakana. Its simple hand motions, repeating structure and shark family characters made it easy for very young children to copy, and easy for adults to parody. Years later the short chorus remains shared as a meme sound, a nursery staple and a shorthand for toddler chaos online.
