A 2D digital illustration in a vintage cartoon style, featuring a grumpy-looking stone tortoise. The tortoise has a cracked, rocky shell covered in moss and tiny plants. Its legs are stubby and sturdy, resembling rough boulders. The expression on its face is slow but annoyed, with heavy eyelids and a slight frown. The background is a soft, checkered beige tone like a game asset sheet. The art style is consistent with cozy, fairy-tale RPG visuals, soft outlines, warm earthy colors, and shading.
