At the top of the Cartoon Style image, place the text: "Happy Birthday, Christian - another year deeper into it!"

Playful, funny underwater cartoon scene in bright, saturated colors with thick black outlines and exaggerated proportions. Center stage: a chubby, big-eyed sea turtle in a tiny party hat and dive belt, grinning as it offers a waterproof birthday cake perched on its shell (glow-stick “candles”). To the left, a goofy scuba diver with oversized fins and a bobbly air tank hovers at an angle, cheeks puffed behind a mask, blowing bubbles like confetti; their regulator doubles as a party blower. A curious school of fish in mini party hats swarm around, forming loose spiral shapes; a pufferfish floats like a helium balloon, tied by seaweed ribbon to the diver’s wrist. The coral reef is lush and candy-colored (coral pinks, tangerine, lime, turquoise), with whimsical shapes like icing swirls and sprinkles; a couple of corals shaped like gift boxes. Sunbeams slice down through teal water, and tiny sparkle highlights glint in the bubbles for extra cheer. Comedic details: a clownfish toots a noisemaker, a shy turtle buddy peeks from behind a fan coral, and a starfish claps.

Small extra text (one short line): on a little driftwood sign nestled in the coral near the bottom, add “Shell-ebrating under pressure!” in a playful hand-drawn style.

Overall vibe: energetic, whimsical cartoon; bold, clean outlines; vibrant palette; dynamic, floaty poses; big expressive faces. Only the two text elements described above. Portrait orientation with roomy top area for the headline.
