陰森實驗室裡的畸形行走大腦怪物

A gargantuan brain with thick, whitish, leathery skin and gnarled, pulsing veins, featuring a large, evil eye at its front that stares menacingly. It sports a wide, toothy evil grin, revealing crooked, yellowed teeth, with the upper eyelid appearing as a long bushy eyebrow and the lower eyelid as sharp teeth scraping the wicked eyeball. Stubby arms and legs sprout from the brain. This walking brain conducts experiments in its evil laboratory, holding test tubes. The lab is filled with strange creatures preserved in jars, peculiar electrical equipment on the walls, and a table with a large, strange, horrible slimy mutant spider strapped down. The lab is full of old style electrical equipment with electrical arcs happening at full power. Cinematic 3D render, octane render, high detail, volumetric lighting, unsettling atmosphere, inspired by H.R. Giger and Zdzisław Beksiński.
