Imagine a vibrant, cartoon-style birthday card, overflowing with colorful, exaggerated features. The scene is set against a backdrop resembling the Berlin Wall, but instead of its historic gray, it's splashed with graffiti depicting surfboards and frisbees, radiating a playful, carefree energy.

In the foreground, there's a giant frothy mug of Stella Artois, tilted slightly with exaggerated size, almost as if the foam is about to spill over. The mug serves as a whimsical table, holding an enormous, cartoonish birthday cake, decorated with "21" candles in bright, bold colors. The cake is covered in a glossy, sugary glaze and topped with little edible surfboards and frisbees.

A cartoon surfer with wild, wavy hair, reminiscent of classic comic characters, rides an enormous wave in the background. The wave, stylized with thick, swirling lines, looks like it's about to crash into the wall, carrying a playful sense of action.

Suspended in the sky, a banner flutters with the name "Mark" boldly printed in dynamic, colorful letters, as if it’s been painted with the same energetic brushstrokes as the graffiti. It flaps in a breeze that seems to come from the motion of the surfing wave, tying the elements together with a lively sense of movement.

Scattered around are playful, oversized cartoon frisbees, mid-flight, adding to the dynamic energy of the scene. Their paths are traced by dotted lines, reminiscent of comic book action, leading the eye around the card.

The color palette is a mix of bright primary colors, with bold reds, blues, and yellows, accented by the rich, foamy whites of the Stella Artois and the iridescent hues of the surfboard decals, creating a vibrant, eye-catching composition.
