This pixel art image depicts an underwater scene centered around a large treasure chest partially covered in sand, surrounded by vibrant coral formations and aquatic life. The chest is positioned in the lower middle of the frame, slightly to the left, with its lid ajar. Two jellyfish are visible, one prominent in the upper center and a smaller one floating towards the right. The larger jellyfish has a distinct bell shape and flowing tentacles. The foreground is dominated by the sandy seabed and various types of coral and aquatic plants, creating a textured, organic border around the central dark space of the water column. The background, above the chest, is a dark void representing the depths, while the upper portion shows a subtle gradient of lighter blue-green, suggesting the surface or a light source from above. The overall composition is framed by the dense coral and rocky structures on the left and right sides, drawing the viewer's eye towards the center. The color palette is limited but effective, dominated by shades of deep teal-blue for the water and shadows, desaturated orange-brown for the coral, sand, and jellyfish, and highlights of lighter sand color. This creates a muted, somewhat dark but warm color scheme characteristic of deeper underwater environments. The overall vibe is one of mystery, exploration, and tranquility, with a nostalgic feel due to the pixel art style. The hidden treasure chest and the floating jellyfish evoke a sense of wonder and the unseen life of the deep sea. There are no text or UI elements visible.
