Create a glossy 3D Chinese co-branded fantasy dessert advertising poster for MIXUE and 迪莫. The scene is a pastel pink-and-blue candy kingdom with soft clouds, sparkling crystal candy, ribbons, floating stars, and two pink fairytale castle towers in the background. On the right, show one cute blue-and-white mascot creature with large glossy black eyes, yellow ear tips, an orange cheek mark, a yellow V-shaped forehead mark, white belly, tiny paws, and a long tail ending in a blue star with a yellow tip; it smiles with an open mouth and hugs an oversized pink strawberry milkshake cup. The cup has a domed clear lid, a pink straw, whipped cream, strawberry sauce sprinkles, many shiny pink tapioca pearls at the bottom, the MIXUE logo in white with a small crown icon, and one printed illustration of the same mascot winking on the front label. In the lower left foreground, include one vanilla soft-serve ice cream cone, one whole strawberry, one yellow star candy, and scattered translucent pink crystals and pearls. Place large bold 3D Chinese headline text in the upper left reading 甜蜜冒险，萌力出发, with the first line in pink and the second line in bright blue, white bevels, drop shadows, sparkles, and a small gold crown above the headline. Beneath it, add a thin decorative line and smaller Chinese collaboration text reading 蜜雪冰城 × 洛克王国 迪莫 联名活动. Use a cute commercial key visual style, highly polished toy-like 3D rendering, soft rim light, dreamy depth of field, high saturation, clean composition, joyful summer-dessert atmosphere, 4:3 horizontal poster format.
