The moon monster is a towering, otherworldly creature with a bulbous, glowing body that shimmers like the lunar surface. Its long, spindly arms end in razor-sharp claws, and its eyes burn with an ethereal, malevolent intensity. A mass of writhing, pulsing tendrils erupt from its head, like a dark, celestial aura. As it moves, the moon monster's body seems to shift and writhe, as if it's perpetually emerging from the shadows of the moon itself. Its very presence seems to draw the light out of the air, leaving only an unsettling, eerie glow.
