A vivid picture of a tired, ancient, weathered turtle man with a shell that is decorated in prominent glowing barnacles across its plates of his shell that are arranged in constellations of the night sky that glow brightly. He appears to wear some sea faring articles of clothing, carries an old three pronged trident and a shield. He has algae on him, He is a sea captain. He is wise, old weathered, ancient, wrinkled and grumpy but the stars on his shell shine brightly
