With Christmas just around the corner at Mossy Bottom Farm, young Timmy goes missing after a botched attempt to get roomier stockings for the flock. As the clueless Farmer tries his luck at selling home-made soda at the local fair, clever and confident Shaun embarks on a dangerous rescue mission, of course, under the nose of Bitzer, the sheepdog. Can Shaun get his little cousin back and save Christmas? —Nick Riganas
