Reindeer are an integral part of Christmas. From the Rudolph the REdnosed Reindeer Christmas special on TV to fancy head bands with antlers to presence on countless overwrought wweters. Most importantly, they pull Santa's sleigh..... except when they don't. It's been a harsh year and sharp winds from the Polar vortex have set all 8 up in bed with colds. Moo better to pull the sleigh than the other most beloved, sweet natured hooved animal is Santa's barn? The cows! We hope this bovine, singing Christmas ecard becomes a beloved new tradition among musical Christmas ecards. See if you can name them all as they hoof their way across the snowy Christmas animated sky!
