"Create a realistic 3D character inspired by a friendly health mascot, designed for kids. The character should have a round, cheerful face with large, friendly eyes and a warm smile. Its colors should be bright and inviting, mainly greens and blues to convey health and vitality. Dress the character in a simple outfit that could include a small cap or a shirt with a health symbol, like a heart or a plus sign. The character should have simple, rounded features to look approachable, with soft lighting and detailed textures to enhance the 3D effect. Place the character against a plain, light-colored background to make it stand out."
