Park Geon-roung, the boy known as "Baby Shark Boy" for his appearance in Pinkfong's globally viral Baby Shark music video, is preparing to launch a K-pop career. The video he starred in as a seven-year-old became the most-watched clip in YouTube's history, amassing more than 17 billion views, giving him a huge built-in profile as he now attempts to transition into the competitive K-pop industry.

His debut is being backed by Pinkfong, the South Korean children's entertainment company behind Baby Shark, which will be hoping to replicate its earlier viral success in a new format. The BBC's Tessa Wong outlines what to expect from the upcoming debut, though it remains to be seen whether the childhood fame that made him a global phenomenon will translate into success as a K-pop performer.
