What Is the 'Baby Shark' Challenge?

The YouTube "Baby Shark" song is attracting headlines again now that there's a viral dance challenge to go along with it. The "Baby Shark" Challenge recently formed on social media and has some adults, much like the "In My Feelings" Challenge, dancing to the "Baby Shark" song.  The tune was produced by Korean kids sing-along YouTube channel, Pinkfong, and a dance version shows two children shaking it up to the hit song.
