It's easily one of the most popular childrens song ever - but now 'Baby Shark' has been given a Christmas themed remix. All of the sharks are there but this time they are joined by a very special guest... Santa!
While it's a hit with the kids, not every parent is on board with it.
"No, no, no! The original was bad enough." said one person.
"How did they light their Christmas lights underwater?" asked another.
If the kids still love Baby Shark, this might be a great way to bring some festive cheer to the singalong.
