Better brace yourselves.

Baby Shark is the catchy YouTube phenomenon that is showing no signs of slowing down. It 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. It has spawned a series of cuddly, singing toys (which seem to be the must-have gift this Christmas) and even featured on this year's Late Late Toy Show.  Now, a brand new version of the viral song Baby Shark has surfaced online - and just in time for the holiday season. The Christmassy track, called Santa Shark, is already proving to be a huge hit The festive take on the super-catchy song introduces a number of new characters, including Santa Shark, Reindeer Shark, and Elf Shark. The new lyrics see the characters make the toys, wrap them up and loading up the sleigh - all followed by 'do, do, do, do, do, do, do' - before swimming off to deliver the Christmas gifts. More than four million people have watched the video since Super Simple Songs shared it on YouTube in late November. https://www.youtube.com/watch?v=u0aAMvvw_co
