Picture this: a whimsical underwater birthday celebration unfolds in a cartoonish, vibrant coral reef. At the center of the scene, a cheerful scuba-diving shark sporting a bright green top hat with "Green Day" emblazoned on it plays an underwater electric guitar, reminiscent of a rock concert poster. This guitar-wielding shark is joined by a group of fish with colorful mohawks, their scales patterned like tartan kilts, playing tiny drums and saxophones.

Nearby, a small table made of coral and adorned with seaweed garlands holds a birthday cake shaped like a bourbon bottle and a wine glass. The cake's frosting glistens with shades of amber and burgundy. Around the table, various marine creatures - a pufferfish wearing a party hat, a grinning octopus with its tentacles wrapped around different flavors of cupcakes, and a turtle with a monocle and a bow tie - are all clinking glasses filled with bubbly seaweed soda.

In the background, amidst the coral and sea anemones, you can see a treasure chest overflowing with gifts wrapped in shiny, iridescent paper, reflecting the light filtering through the water. Bubbles ascend from the chest, creating a path leading to a banner that reads "Happy Birthday!" in a whimsical, hand-lettered style, fluttering gently as if caught in an underwater breeze.

To the side, a couple of dolphins leap joyfully through a hoop made of kelp, each holding a sparkler in their mouths, sending a spray of glowing bubbles into the water. A school of fish forms a conga line, their fins synchronized perfectly as they weave through the scene.

Overall, this underwater birthday bash blends the carefree energy of a rock concert with the laid-back vibes of an aquatic wonderland, bringing together elements of scuba diving, Green Day, bourbon, wine, and sharks in a hilariously unique and visually rich cartoon tableau.
