Cute Mermaid Puppy Underwater Game Screen

A bright, fantastical 2D underwater game scene, presented in a delicate children's animation style, is shown as a full-screen level screenshot within a rounded rectangular game viewport. The background features a colorful coral reef, with a light-colored pebble path winding from the foreground to the center of the sandy seabed, creating a sense of depth. Sunlight streams down from the clear blue water, and numerous tiny bubbles float in the scene. Soft, toy-like coral reefs and pink, peach, lilac, turquoise, and mint-colored marine plants surround the path, flanked by rock formations. Two starfish are placed in the foreground: a purple starfish on the lower left rock and a pinkish-orange starfish in the lower right. Two translucent pink jellyfish are added, positioned on the left and right sides of the screen respectively, emitting a soft glow. Six glowing pink clam shells are scattered along the path and around it, each radiating a soft magical halo. Four collectible golden-orange shells with pearl centers are placed near the central game area. Add a large purple balloon-shaped jellyfish obstacle with a white outline and short tentacles to the lower left center and middle right positions respectively. In the left-middle foreground, place an adorable mermaid puppy character inspired by the preschool animation Rescue Dog: a small, smiling dog face, large, expressive eyes, light brown and cream fur, a pink headdress, and a cyan mermaid tail, its posture playful and cheerful, as if moving forward. On the right, add a faintly dotted circular target marker above the environment. Overlay a simple Chinese mobile game UI: two white rounded capsule buttons in the upper left corner, displaying "Collect Shells" and "1/5" respectively; a white circular pause button with "II" in the upper right corner. Place three white rounded command buttons at the bottom center, with blue-gray text: "Arrow Keys/WASD", "Space/Enter: Bubble", and "Esc Return to Map". The overall visuals have a strong sheen, soft lighting suitable for children, high and balanced color saturation, creating a dreamy coral reef atmosphere, and a simple composition consistent with the art style of casual games.
