An ancient forest guardian boss creature in a stylized cartoon style. Its head is a massive, weathered mushroom cap covered in moss and cracks. The body is tall, humanoid, and made of bark, roots, and fungus, with large twisted branches growing from its shoulders and back like antlers. Glowing green patterns pulse faintly along its limbs. Its eyes glow a deep green, exuding timeless wisdom and sorrow. The creature looks extremely old, with its posture slow and heavy, as if carrying centuries of burden. Vines and lichen drape from its arms and legs like robes. It radiates an aura of ancient power and forest magic, suited as a wise but dangerous boss in a magical forest environment.
