Art style: 3D Pixar.
A charismatic 6-year-old boy with messy, sun-kissed blonde hair and bright, mischievous blue eyes. He has a playful, gap-toothed smile and rosy cheeks. He is initially seen in mismatched, slightly small grey pajamas, looking rumpled and energetic. Later, he wears a vibrant mustard-yellow cotton tracksuit with white stripes and clean white sneakers. His energy is infectious and bold. The background is a contemporary child's playroom filled with colorful wooden toys and soft natural light. He has a lean, active build typical of a child his age who loves to run and play.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "3D Pixar" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "3D Pixar". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "3D Pixar" idiom, not in any other medium.
