This Birthday card drops you into an underwater scene filled with bright color and party energy 🎉. At the center sits an irregular message bubble edged in red and orange with small golden studs, like a tiny marquee sign. Inside the bubble, deep purple text reads “HAVE A HAPPY BIRTHDAY,” set large and easy to spot. Around it, wide-eyed cartoon fish in yellow, orange, green, and purple glide past with gentle smiles, some swimming close together as if sharing a friendly, affectionate moment. Turquoise water surrounds them while soft beams of light stream down from the surface, catching pearly bubbles as they rise. Along the bottom, stylized coral and seaweed in fuchsia, deep orange, and rich green curl and sway, adding a cozy, lively backdrop for the birthday message 🎂. The seabed is dotted with rounded shapes and clustered coral branches in layered pinks and oranges beneath the floating bubble sign.
