Design a creature with the torso of a massive, gnarled tree knot, its texture resembling weathered bark, with deep grooves and cracks. In the center of the knot, there is a large, glowing single eye, pulsing with an eerie yet mystical light, exuding an ancient, wise presence. The arms and legs of the creature are twisted and knotted tree branches, their bark rough and uneven, stretching outward in an asymmetrical, wild formation. The creature's branches are adorned with flickering Christmas lights, tangled among the limbs, some glowing brightly, while others flicker erratically, adding a magical yet spooky ambiance. The branches should have a life-like quality, with subtle movement as if they breathe in the winter air.
