This design shows an underwater scene washed in turquoise light, with sunbeams filtering down like gentle spotlights 🎉. In the center, a plump pink amphibian-like creature smiles with rosy cheeks, its friendly gaze aimed toward the viewer as if sharing a sweet moment. It wears a purple party hat dotted with lighter spots, adding a fun touch without overwhelming the scene. The creature holds out a slice of pink-layered cake, and a single candle glows warmly on top 🎂. Near the upper area, “HAPPY BIRTHDAY!” appears inside a pink speech bubble, set in clear uppercase lettering that stands out against the water. Around the sandy seabed, textured corals in mixed colors sit like a cozy little neighborhood, while small golden-yellow fish drift nearby and bubbles rise toward the surface. Soft shadows fall beneath the creature and across the sand, and the bright pink bubble sits slightly above and to one side of its head.
