Create a cute, cartoon-style Futalognkosaurus 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 and rounded for a kid-friendly look. 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
