A lively 3D chibi fantasy birthday illustration set above glowing moonlit waves at night. Humanoid mermaid spirits appear in three evolving forms, gathering around a large ocean-themed birthday cake. Floating bubbles, sea flowers, and soft wave lights fill the scene. An original “Happy Birthday” fantasy font floats above, combining ocean motion with rounded guinea pig–inspired shapes for a playful and dreamlike celebration.
🔹 Story Description
When the sea grows quiet, the celebration begins.
Under a sky painted with deep blues and silver light, gentle waves roll like breathing dreams. From the surface of the water, the Mermaid Spirits rise—humanoid beings born from moonlight, tide, and shared joy.
This night is different.
At the heart of the waves floats a large birthday cake, balanced on shimmering water and decorated with shells, glowing pearls, and soft candlelight. Around it gather seven or more mermaid spirits, each moving with playful energy—some splashing lightly, others floating above the water, laughing as bubbles drift into the night.
Above them, the words “Happy Birthday” glow softly.
The letters curve like waves, rounded and gentle, with subtle shapes inspired by chubby guinea pig cheeks and ears—softening the ocean theme with warmth and charm.
This is not a battle.
Not a legend of power.
It is a night where the sea itself pauses—
just long enough to celebrate a birthday.
