At the top of the Cartoon Style image, "Happy Birthday Sparky" in big, bouncy bubble letters with thick black outlines, glossy gradient fill, and confetti accents.

A vibrant, funny cartoon party scene packed with playful butt-themed gags: center stage, a huge anthropomorphic peach with a grinning face, party hat, and sneakers dances with exuberant wiggles, its two rounded “cheeks” outlined in chunky black lines and surrounded by comic motion swooshes. A conga line of smiling peach- and balloon-butt characters in jaunty party hats shimmies behind it, all with exaggerated proportions, starry eyes, and goofy poses. To one side, a frosted peach-shaped birthday cake (two rounded tiers) is topped with sparkling lightning-bolt candles that crackle and fizz, nodding to “Sparky.” A cheerful corgi with a fluffy, over-the-top backside bounds by trailing streamers. Confetti explosions, starbursts, and ribbons fill the air. Background: radiant teal-to-hot-pink burst with playful halftone dots. Style: thick outlines, cel-shaded, bright saturated colors (neon pinks, tangerine, sunny yellow, aqua, electric purple), glossy highlights, whimsical, energetic poses.

At the bottom, add a small cheeky caption in a playful font: "Hope your day is a crack-up!"
