Create a vibrant, underwater cartoon-style scene full of humorous and festive details. A zany birthday pool party is happening beneath the waves, featuring quirky cartoon sea creatures mid-celebration. In the center, a cheerful shark with a big grin wears a bright birthday party hat and a snazzy polka-dot bow tie, floating proudly behind an elaborate buffet table crafted from coral and sea sponges, piled high with marine delicacies like seaweed cupcakes, clam cookies, and krill kebabs.

Surrounding the buffet are party-going sea animals—dancing jellyfish in hula skirts, octopuses tangled in party streamers, and seahorses sipping from tiny conch shell drinks with cocktail umbrellas. Add lots of vibrant party balloons anchored to the ocean floor and bubble trails rising to the surface.

In the background, colorful cartoon fish (wearing swim goggles and party hats) are swimming in coordinated formation. They blow festive bubble letters that spell out **"Gefeliciteerd Niels"** in a bubbly, celebratory font, contributing to the joyful, hilarious tone of this underwater bash.

Make the colors bright, saturated, and playful. The mood is quirky, light-hearted, and unmistakably festive.
