An old broken pirate barrel resting on the seabed, partially buried in sand and surrounded by small rocks and seaweed. The wooden planks are cracked and waterlogged, held together by rusty iron bands. The barrel is split open on one side, revealing glittering pirate treasure spilling out: gold coins, ornate rings, a silver goblet, and a string of pearls. Small fish swim nearby, and tiny air bubbles rise from the barrel. Covered in patches of algae and coral growth. Underwater lighting, soft blue tones, realistic texture detail, fantasy adventure style., #ocean#
