You slither up through the ground, snap your jaws around skiers, reindeer, and clueless holiday shoppers, then dive back under to dodge the choppers and tanks hunting you. Every bite makes you longer and deadlier, so you kep growing into a festive nightmare that swallows whole buildings by the end. Eat enough and you unlock bigger targets, racking up your score with every crunchy gulp. Think you can become the biggest worm this Christmas?
