Joyous Aquatic Birthday Card

This design shows an underwater scene built around large “HAPPY BIRTHDAY” lettering centred on the card in deep pink, with the words spaced wide so the sea life can curl in around them 🎉. A rose-toned octopus floats near the upper left, its tentacles looping towards the message as if reaching out with friendly affection. On the upper right, a smooth blue whale-like swimmer drifts calmly, angled inward as though returning the octopus’s attention across the page. Nearby, an orange jellyfish trails thin, soft strands that hang beside the text like gentle streamers 🎂. Along the lower area, a green-shelled sea turtle moves through tall sea grass, its patterned shell adding texture among blue and green coral shapes. Two orange starfish sit near the bottom corners, warming up the cooler water tones and framing the scene like a pair of quiet companions. Small bubble circles in pale blue and white rise across the background, scattered around the coral and seaweed on a bright white field.
