The viral hit is the sort of song that first takes off with small children before finally popping up on their parents' radar and then getting old pretty fast.
Baby Shark was created by a YouTube channel called Pinkfong - a South Korean channel for kids, which makes videos of sing-along songs and dances.
The video was originally released back in November 2015 but only started to spread globally this summer.
The song is now insanely popular with the under-8 set all around the world and have even appeared in the charts in the UK - but is now at the centre of a row about sexism in the country where it originated.
The Kyunghyang Shinmun newspaper slammed the song as being sexist back in January.
While the English version doesn't have that many real words, the paper reported that the Korean lyrics describes Mummy Shark as "pretty”, Daddy Shark as “strong”, Grandma Shark as “kind” and Grandpa Shark as “cool”.
In an editorial, it claimed that the song reinforced sexist prejudices.
Meanwhile parents have been warned about the dangers of taking part in the 'Baby Shark Challenge', which has seen some people getting out of a moving car to break into the routine.
