Design a black-and-white coloring page that showcases a lively scene in the African savanna forests. Include at least three rhinos, each engaged in different playful activities such as running, jumping, or interacting with each other. Surround them with characteristic savanna vegetation like acacia trees, grasslands, and perhaps a watering hole. The illustration should be simple and child-friendly, with bold outlines and ample space for coloring. Since this is a coloring page for children, ensure that the design is suitable for young artists to fill in with colors. --no gray color q 2 --ar 2:3
