People around the world were enraptured with 'Baby Shark' last year.
Every corner you turned, a kid would be screaming it at the top of their lungs while doing the funny hand movements.
Just when we thought 'Let It Go' had died and we were at peace, 'Baby Shark' came around and we were plunged into another nightmare. But naturally it faded into the annals of catchy songs and silence was restored.
Yep, that song we all love to hate (or hate to love) is being revived by Netflix and turned into an entire TV series.
But fear not, it's not going to just be half an hour of that song being blasted out of your telly. Pinkfong, the South Korean company that created 'Baby Shark', says they'll be releasing short videos on the streaming service this year.
SmartStudy, which owns Pinkfong, Chief Financial Officer Seungkyu Lee has told Bloomberg the secret behind their success.
"We've added the 'K-pop factor' into our songs, such as very trendy beats and upbeat rhythms," he said.
"If you've ever heard of 'Baby Shark,' you might feel the importance of community. In a group, we should walk or swim together."
He added that he really enjoyed the film Madagascar, hinting that their next viral hit could move away from the apex predators of the sea and focus more on penguins.
Please God no.
While 'Baby Shark' was intended for kids, it didn't stop older people getting into the do do do do do jam. Actually, for some people it was a bigger hit than Oasis or The Arctic Monkeys.
One 18-year-old partying it up in Ibiza decided to pay homage to the hit song by getting it tattooed onto her goddamn arm.
She got the words 'baby shark dodododododo' down her forearm and, understandably, her dad is fuming.
Chloe, from Lancaster, paid more than £100 to be branded with the song that's been viewed more than a billion times on social media.
However, her dad has not seen the comedic levels of the tattoo and is not impressed with his daughter's new ink addition.
She said: "My dad's not very happy - he's not seen the funny side of it at all."
But despite her dad being unimpressed, she says her mum does see the funny side of it and is even considering getting a 'Mummy Shark' tattoo. Now that would be awesome.
