Create a cute, cartoon-style Jobaria for a children’s coloring page. Make it friendly-looking with big, round eyes and a gentle smile. Show its long neck, small head, pillar-like legs, and one single long tail. Keep the body soft, rounded, and approachable for kids. Line art only, no colors, no background, clear outlines for easy coloring. The pose should be standing or walking, playful and simple for kids to color.
