The main artwork displays a cross-section of a subterranean lair designed as a complex maze. At the very top, on the grassy surface, a cheerful birthday party is underway with guests, a table, and colourful bunting. Below this, the earth is excavated into a series of interconnected tunnels and chambers filled with hidden rooms, secret passages, and whimsical equipment.
Inside the maze, one can find a variety of distinct areas, including a security monitoring room with screens, a library with bookshelves, a kitchen, and a central throne room where a character with a crown sits. The tunnels are decorated with scattered rocks, hanging light bulbs, and birthday-themed items like balloons and presents. Some sections of the maze appear to be dissolving or incomplete, represented by missing, jagged edges that look like loose pieces waiting to be filled in.
The overall aesthetic is a vibrant, retro pixel-art style. The color palette relies on a warm, earthy red-orange for the dirt and tunnel walls, contrasted against the deep, dark purple vertical stripes of the background. Soft lighting glows from the various rooms, casting an inviting atmosphere throughout the subterranean structure. The composition is highly detailed, encouraging the eye to follow the winding paths from one curious room to the next.
