A stylized cartoon boss monster in T-pose: a tall, humanoid mushroom made of smooth, dark obsidian glass. Its chest features a large circular mirror surface, flawless and glowing faintly—reflecting the world with eerie clarity. The mushroom cap is dome-shaped, like a smooth metallic umbrella, rippling with ghostly silver light. The face is absent—only a continuation of mirrored glass, expressionless and warped. Thin glowing cracks run across its limbs like ancient fractures. Long arms end in reflective blade-like fingers. Its legs are slim and rigid, with crystalized roots at the feet. The entire body radiates silent energy, cold and mysterious. Color palette: obsidian black, cold silver, ghost-blue.
