Take the single character in the image and modify them while keeping all their original traits, design style, and artistic integrity intact. Change their skin to a vibrant lime green. Add a seamlessly integrated third eye in the center of their forehead between their existing two eyes. Place a single lime green antenna protruding naturally from the top of their head. Ensure the modifications blend smoothly and look cohesive while preserving the character’s original style, proportions, clothing, and overall identity.
