Penny Discovers Puzzle World

Black-and-white line art for a children's coloring book. A young girl named Penny, around 6 years old, with curly bobbed hair and round glasses, wearing overalls with puzzle patches and sneakers. She is clever, thoughtful, and curious. The style is imaginative and whimsical, with bold outlines and a pure white background. Include a thin-outline title at the top that says: “Penny Discovers Puzzle World” so children can color it. Scene: Penny stands before a glowing puzzle-shaped doorway with sparkles and gears around it.
