The kids' song Baby Shark is swimming with the big fish on the pop charts. The song about a family of sharks hunting for their next meal comes in at number-32 on this week's Billboard Hot 100. It had almost 21-million streams last week. That's in addition to the more than two-billion views it's run up on YouTube.
The song and accompanying dance were around for decades before South Korean children's educational company Pinkfong spun its successful Baby Shark video into a series of animations featuring penguins, apes, and lions. From there, K-pop heavyweights like Girls' Generation and BLACKPINK jumped in on the dance challenge as the video swept across much of Southeast Asia.
