‘Baby Shark’ has over 1.6 billion views on YouTube, and having just entered the UK Top 40 Chart at number 37 – two places closer to number 1 than Cardi B’s I Like It, mind you – we can’t stop singing PinkFong’s catchy Baby Shark (doo doo, do-do doo doo) song. The Korean children’s YouTube channel PinkFong reports that, across all its platforms, the baby shark series has been watched over 3.3 billion times.
