A stylized 3D anatomical human skeleton character with a friendly, cartoonish expression. Smooth matte off-white bone material, not glowing or translucent. The skull has a warm, cheerful expression with a subtle smile showing the upper row of teeth, and large expressive cartoon-style blue eyes with visible pupils and eyebrows, giving it a lifelike, approachable, almost human personality — like a friendly mascot rather than a scary skeleton. Detailed ribcage, spine, and pelvis with realistic bone texture. Standing in a relaxed pose, upper body and head facing the camera. Soft indoor lighting, blurred office or laboratory background with window blinds and soft blue-toned light. Vertical 9:16 format, hyperrealistic yet slightly stylized 3D render, consistent character design for a recurring educational video series, Pixar-adjacent character appeal but anatomically accurate bone structure.
