Design a colorful and playful 3D scene where the numbers 0 to 9 are cleverly hidden within various elements of the environment. The setting could be a magical forest with trees, animals, flowers, and clouds. Each number should be subtly integrated into the design, such as in the branches of trees, shapes of rocks, or patterns on leaves, making it challenging yet fun for students to find. Ensure the colors are vibrant, with a cheerful and whimsical atmosphere, and use a white background to keep the focus on the hidden numbers. --niji 6
