Front and center of the birthday card, we have Robin, the superhero sidekick turned quirky detective. He's wearing a classic detective trench coat over his iconic red and green superhero outfit, which peeks out with its bold colors. His green domino mask is still in place, adding that touch of his heroic persona to his new detective role.

Robin is holding a sleek metal detector, its metallic rod glinting under the bright sun. The detector’s screen is sophisticated, with a small radar display showing a cartoonish treasure chest symbol. The handle of the detector is a glossy black with silver accents, making it look both high-tech and stylish.

The scene is set on a sandy beach, with footprints leading up to Robin’s position. There are colorful beach towels scattered about, in shades of azure blue, sunny yellow, and cherry red. A few beach balls are in the vicinity, their panels a vibrant mix of rainbow colors.

In the background, the ocean waves are crashing gently onto the shore, with the sea painted in deep azure hues, dotted with sparkles from the sunlight. A cluster of palm trees to the left sways in the breeze, their fronds a lush green against a cerulean sky.

Above Robin, a whimsical banner stretches between two palm trees, its fabric a crisp white with the name “Robin” written in bold, green letters reminiscent of comic book fonts. This banner adds a playful touch to the detective scene.

Scattered around the beach are various 'detective finds' - a shiny gold coin half-buried in the sand, an old-fashioned compass, and a large, decorative conch shell. To the side, a small birthday cake sits on a portable table, its icing done in superhero colors with red, green, and yellow sprinkles and a single candle flickering merrily in the gentle breeze.

The overall scene is lively with lifelike details, capturing both the spirit of a birthday celebration and Robin’s unexpected role as a detective on a sandy shore adventure.
