"Master Splinter, the wise rat, standing confidently in a dimly lit sewer. He has a vibrant pink pompadour hairstyle, slicked back and contrasting with his traditional robes. The sewer walls are damp and covered in graffiti, with water dripping from pipes overhead. A faint greenish glow from the tunnel lights illuminates his face, highlighting his sharp eyes and weathered fur. The atmosphere feels gritty and urban, with shadows casting dramatic lines along the curved walls of the underground labyrinth.
