Of all the Christmases, the usually careless but well-meaning primaeval sloth, Sid, picked this particular one to ruin entirely, now that Manny's young daughter, Peaches, has grown up. With the family's precious heirloom smashed into pieces and a place in Santa's long list of naughty kids rightfully earned, Sid along with Crash, Eddie, and Peaches set out on a journey all the way up to the frozen North Pole, to make things right again; however, Sid is bound to do more harm than good. Will Manny and his team pull off a real miracle to save Christmas?
