Front and center of the card is a colossal birthday cake shaped like the Colossal Titan from "Attack on Titan." The cake, in creamy pastel colors of soft pinks and blues, towers over a whimsical landscape. Its icing is delicately piped to mimic the muscular details of the Titan, with sparklers serving as the Titan's eyes, blazing with celebratory sparkles.

In the foreground, Tanjiro Kamado from "Demon Slayer" is depicted in an exaggerated cartoon style, wielding his sword made of bubblegum, which twists in surreal loops as if caught in a candy tornado. The sword's hilt glimmers in hues of metallic green and gold, catching light like a disco ball.

Flanking Tanjiro, Denji from "Chainsaw Man" sits nonchalantly on a cake stand, his chainsaw transformed into a fun confetti blaster. The chainsaw's jagged edges are replaced with swirling ribbons and colorful streamers, ready to rain a cascade of paper joy at a moment's notice.

Nearby, Deku from "My Hero Academia" dons an oversized party hat resembling his iconic green mask, the hat tipping jauntily to one side as if defying gravity. His gloves are replaced with giant foam fingers pointing upwards, painted in vibrant shades of red and yellow, symbolizing high-fives ready for the birthday hero.

In the background, the beloved Jake the Dog and Finn from "Adventure Time" make a cameo, with Jake stretched into an inflatable bouncy castle and Finn jumping gleefully, balloons tied to his sword hilt. The balloons, in kaleidoscopic colors, create a polka-dotted sky against a canvas of bright, sunny yellow.

The sky itself is dotted with fluffy cotton-candy clouds, each in pastel shades of lavender and mint green, reminiscent of Charles Schulz’s gentle lines, giving a whimsical, dreamlike backdrop akin to "Little Nemo in Slumberland."

Around the edges of the card, swirling cartoonish doodles of confetti and stars, drawn in the style of Bill Watterson, add an energetic frame, leading the eye back to the fantastical birthday celebration at its heart.
