Art style: Pixar-like 3D.
Full-length view, the entire figure visible from head to feet, standing upright, figure centered in a cozy warm apartment interior that stands in for the inside of a human body — soft beige walls, red and green accents in the background. Potassium is a cheerful friendly character shaped like a plump rounded mineral person with smooth soft skin in a warm golden-yellow tone, big bright expressive eyes, rosy cheeks, a wide welcoming grin, small neat ears and a tiny rounded nose. Athletic but soft build, a bit shorter and chubbier than average, radiating warmth and friendliness. He wears a bright sunny-yellow zip-up tracksuit — matching jacket and pants with white side stripes and a small zipper — plus clean white-and-yellow sneakers on his feet. Relaxed, open posture, one hand raised in a friendly wave, upbeat approachable expression.
