Whimsical Seahorse Birthday Card

Designed with an underwater scene framed by a strong orange rectangle, this card sits on a pastel green and white striped background that feels light and friendly 🎉. In the centre, a stylised seahorse-like creature shows bright yellow and green stripes, a spiky purple crest, and a tightly curled tail. Its wide blue eye and small pink mouth give it a sweet, affectionate look, like it’s leaning in to greet someone it cares about. Behind it, the water is a soft light blue with bubbles floating upward in a gentle drift. Deep green sea plants curve in from the sides, almost like they’re wrapping around the little creature in a quiet, supportive way. The words “Happy Birthday” appear above the frame in teal lettering, placed prominently so they’re easy to spot 🎂. Along the bottom edge inside the frame, rosy pink coral shapes form a soft base beneath the swaying greenery.
