Front and center of the card, there's an adorably cartoonish otter standing upright on its hind legs, reminiscent of the playful style of Charles Schulz or Bill Watterson. The otter is grinning broadly, with exaggeratedly large eyes and tiny whiskers that give it a cheeky appearance. It’s holding a brightly decorated birthday cake in its front paws, balanced perfectly. The cake is multi-tiered, dripping with vibrant icing in a rainbow of colors—reds, yellows, blues, and greens—with a single, oversized candle perched on top, lit with a whimsical, spiraling flame.

Behind the otter, there is a playful splash of water, like a tiny, animated fountain that bubbles up joyously, inspired by the dynamic, flowing lines often seen in Osamu Tezuka's works. The water is drawn in cool shades of blue and teal, with a few droplets suspended mid-air, creating a sense of movement.

Above the otter, in a speech bubble styled like something from Hergé's Tintin, the words "Happy Birthday Alex!" are inscribed in bold, comic sans-like font, filled with vibrant colors and outlined in black to make the text pop.

To the left and right of the otter, scattered like confetti, are a series of large, cartoonish hearts in various shades of pink and red, reminiscent of the whimsical humor found in Gary Larson's cartoons. They float buoyantly, adding a playful touch to the scene.

The background is a simple, pastel-colored wash—perhaps a soft lavender or pale yellow—allowing the vivid colors of the otter, cake, and water to stand out starkly. The scene is framed by a subtle, sketched border that adds an extra touch of classic comic strip charm, a nod to Winsor McCay's elegant line work.

Overall, this colorful birthday scene is bursting with exaggerated features and lively details, ensuring it captures the eye and delights anyone who receives this card.
