The scene is set in a vibrant, cartoonish landscape with a touch of cosmic whimsy, blending elements of Warhammer’s grim dark universe with a playful birthday celebration. The background is a starry night sky, with exaggeratedly large, round, and colorful planets. A massive, sickly green Great Unclean One stands at the center, its corpulent form rendered with exaggerated folds and bulges, like something out of a comically grotesque dream.

Around this grand creature, a group of mischievous Nurglings frolic. They are tiny, impish figures with cheeky grins, rendered in varying shades of vibrant green, some with tiny party hats precariously perched atop their heads.

In the foreground, a colossal birthday cake towers almost to the Great Unclean One's waist. The cake is an extravagant affair, iced in sickly greens and purples with drizzles of slimy goo that glisten under the starry sky. Candles on top burn with an eerie, yet cartoonishly vivid flame.

The Great Unclean One holds a festively wrapped gift in one hand, its fingers comically large and exaggerated, as if struggling to grasp the small object. The gift wrap is bright purple with yellow polka dots and a comically oversized red bow.

Balloons float nearby, their strings held by jubilant Nurglings, each balloon a vivid shade of neon green or toxic orange. They add a sense of buoyant whimsy, contrasting the grotesque centerpiece.

A colorful banner, held aloft by two jolly Nurglings, stretches across the top of the scene. Written in bold, playful letters, it reads “Happy Birthday Sam!” Each letter is uniquely styled, reflecting the chaotic yet cheerful nature of the gathering.

The style is a blend of Charles Schulz's clean lines, with the expressive exaggerations reminiscent of Bill Watterson’s playful forms. The palette is inspired by R. Crumb’s vibrant underground comix, bringing an unexpected pop to the typically grim Warhammer theme, making it both amusing and visually captivating.
