The original Baby Shark video, created by Korean kids' channel Pinkfong.

If you're the parent of a toddler, you'll probably know about the annoying Baby Shark YouTube video. And now it seems to have taken on a life of its own with a challenge.

With over 3.3 billion views, the original Baby Shark video, created by Korean kids' channel Pinkfong, has reached titanic proportions, so it was only a matter of time till it morphed into something more.

So the Baby Shark challenge works like this: people getting out of moving cars and dancing while being filmed - similar to the "in my feelings challenge" or the "kiki challenge".

In the Baby Shark version, they dress up as sharks and dance along as their cars move.

But now experts are warning against it. 

Cyber safety expert and child psychologist Jordan Foster told The New Daily: "It’s simply dangerous to be jumping out of your moving car to perform this dance."

Despite the warning, people are still posting them under #babysharkchallenge.
