A polished 2D children's animation game screen mockup inside a rounded-rectangle viewport, featuring a whimsical underwater coral reef. At the left-center foreground swims [a cute mermaid puppy character with light brown and cream fur, large expressive eyes, a pink head accessory, and a shimmering teal fish tail in a cheerful swimming pose]. A winding pale stone path stretches across the sandy seabed from the foreground into the distance. The scene is filled with soft, toy-like coral and sea flora in pastel pink, peach, lavender, turquoise, and mint, along with rocky ledges on both sides. Across the scene are [2 starfish (purple on the left rock, pink-orange on the right), 2 glowing translucent pink jellyfish, 6 glowing pink clamshells emitting soft auras along the path, 4 golden-orange pearl shells, and 2 large purple balloon-like jelly obstacles with dangling tentacles]. Sunbeams filter through clear turquoise water alongside floating air bubbles. On the right, a faint dashed circular target marker hovers above the path. Casual mobile game UI overlay in Chinese: top-left white rounded pill buttons showing "[收贝壳]" and "[1/5]"; top-right circular pause button showing "II"; bottom-center rounded instructional buttons displaying "[方向键 / WASD]", "[空格 / 回车：泡泡]", and "[Esc 回地图]". Bright, glossy, pastel-balanced palette with soft lighting.
