dreamy fairytale logo animation

Referencing the image, create a gentle and dreamy logo appearance animation. Start with soft pink and light blue light gently and warmly enveloping a black background, then the logo slowly floats up to represent a weightless dream world. Small stars, hearts, and bubbles drift around to create a cute fairytale atmosphere, and the logo is completed with a sense of warmth, wrapped in pastel colors (pale pink, light blue, and yellow). Finally, the logo pulses slowly and is displayed stably and gently. Gentle, fairytale, fluffy.
