Front and center, the card features an oversized, colorful birthday cake that towers to the top of the card, whimsically detailed with thick, creamy layers of vibrant pink and sky-blue frosting, with exaggerated swirls and dollops. The cake's surface is adorned with large, playful polka dots in various eye-popping hues like sunny yellow, lime green, and electric purple, each dot nearly the size of a cherry.

Bursting out from the middle layer of the cake is an eccentric cat, its features exaggerated to the max, reminiscent of the lively style of Bill Watterson or the whimsical chaos of Gary Larson. The cat's fur is a kaleidoscope of bright orange with stripes of neon purple. Its wide, wild eyes are as big as saucers and its whiskers stretch out in a comically spiky manner, extending far beyond its face. The cat's mouth is agape, filled with impossibly large, gleaming white teeth, giving a nod to the exaggerated features found in Osamu Tezuka's work.

The cat, mid-leap, clutches a cartoonishly over-the-top, oversized machine gun that shoots not bullets but a cascade of multi-colored confetti and streamers, giving the scene a festive flair. The machine gun itself is decorated with rainbow stripes and has an exaggeratedly large barrel, with a handle reminiscent of classic Looney Tunes humor.

In the background, a scene of cheerful mayhem unfolds in a style similar to the playful chaos of Charles Schulz. Cartoonish balloons in every shade of the rainbow float at different heights, some tied to whimsical creatures like mini pink elephants and turquoise birds with long, silly necks. Brightly colored party hats, over-the-top in size and adorned with giant pom-poms, sit atop a gaggle of cartoon animals that peer curiously at the cake, their features exaggerated and silly, as if plucked from a Far Side illustration.

The ground is strewn with oversized, brightly wrapped presents with exaggerated bows and patterns that range from bold stripes to quirky polka dots. The backdrop is a simple, pastel-colored sky with a few fluffy, oversized clouds dotting the horizon, reminiscent of Hergé's clean and colorful style, ensuring the focus remains on the chaotic and humorous central scene.

Overall, the illustration is a riotous celebration of color and whimsy, capturing the essence of an utterly unforgettable birthday surprise with a delightfully chaotic and cartoonish flair.
