Designed with a cheerful underwater scene, this card features a rounded, light blue sea creature drifting through a calm ocean, its belly marked with faint stripes and its back dotted with small purple spots. A spiraled horn in soft lavender and pink rises from its forehead, giving it a sweet, storybook look as it turns toward the viewer with bright eyes, rosy cheeks, and a friendly smile 🎉. The deep teal and green background forms wavy layers like slow currents, creating a cozy setting that feels like a gentle hug shared between friends. Small bubbles float around the creature, and tiny four-pointed golden stars sparkle nearby like little signals of celebration 🎂. Along the bottom, puffy purple cloud-like shapes dusted with tiny white specks resemble dreamy underwater plants, adding softness and depth. The words “Happy Birthday!” appear in white near the upper right, standing out clearly against the darker water tones. Around the creature, the bubbles and golden stars are scattered unevenly, with the brightest cluster sitting just above the purple shapes near the lower edge.
