Front and center, Spiderman and Batman are engaged in a playful tug-of-war with a gigantic, comically over-the-top birthday cake. The cake towers high, boasting exaggerated layers in bright, bold colors—think vibrant red, electric blue, and vivid yellow—with swirling frosting and oversized, twinkling candles.

Spiderman is on the left, playfully pulling one end of a stretchy, gooey web that's anchored to the cake's base. His eyes are wide, and his head is slightly larger than normal, reminiscent of Charles Schulz’s playful proportions. His suit is a vivid red with bold black lines outlining the web pattern.

On the right, Batman is tugging at a massive, comically long batarang that's looped around the cake. His cape flutters dramatically, oversized to add whimsy, with exaggerated pointy bat-ears that almost reach the sky. His suit is a deep, dark gray, contrasted with a bright yellow utility belt and emblem.

Above them, a festive sky is filled with fluffy, cartoon clouds, and a bright banner stretched across the top reads "Happy Birthday Tommaso!" in big, bold letters that resemble Gary Larson's signature style, playful and slightly wobbly.

In the background, a series of colorful skyscrapers line the horizon, their tops slightly tilted and humorous, echoing the playful cityscapes of Bill Watterson’s work. Scattered around are tiny, animated elements: a small group of birds in the sky wearing tiny superhero masks, and a parade of ants carrying a miniature slice of cake, a nod to R. Crumb’s attention to peculiar details.

Throughout the scene, add tiny Easter eggs like a small Astro Boy action figure peeking out from behind a cake layer, a Calvin-like stuffed tiger sitting atop the cake, and a speech bubble coming from a cloud saying "Zap!" in Hergé’s clean, clear lines.

The overall composition is lively and bustling with exaggerated features, bold colors, and humorous details, combining elements from beloved cartoon styles for a uniquely engaging birthday card design.
