ral-apoctvisn, dark, chiaroscuro, low-key, Illustrate a whimsical scene featuring a rubber duck donning a flamboyant pirate costume, set against the backdrop of a vibrant Caribbean harbor. The rubber duck's costume is elaborate, with a tricorn hat perched jauntily atop its head, a billowing white shirt, and a crimson sash cinched around its waist. Tiny, intricate details like a miniature eyepatch and a tiny cutlass tucked into a belt add to the pirate aesthetic. The rubber duck floats gracefully in the crystal-clear waters of the harbor, surrounded by colorful fishing boats with billowing sails and quaint seaside buildings painted in pastel hues. Palm trees sway gently in the tropical breeze, and the azure sky is dotted with fluffy white clouds. The scene exudes a sense of whimsy and adventure, as the pirate rubber duck surveys its domain with a playful glint in its eye.
