Design a collection of simple and delightful coloring book pages featuring various animals, perfect for children aged 3 and above. Create basic outlines of beloved animals like a gentle elephant, a playful monkey, a graceful giraffe, a brave lion, and a charming zebra. Ensure that the outlines are clear, easy to follow, and void of any colors, allowing young artists to use their imagination. Craft each animal with simple shapes and lines, making them approachable and engaging for little hands to color. These coloring pages should capture the essence of each animal's character while providing an enjoyable and age-appropriate coloring experience for young children.
