Ectoplasmic HAPPY HALLOWEEN Slime Sculpture

3D render, photo-quality, “HAPPY HALLOWEEN” formed by suspended ectoplasmic slime: semi-transparent, bioluminescent green with rolling internal refractions and tiny trapped bubbles; faint particulate swirls within each stroke; soft top light creates glossy highlights, cool ambient glow bleeds onto a matte lab-slate; playful paranormal vibe, full-frame.
