Pet Shark

Pet Shark is a real-time 3D aquatic sandbox and virtual pet simulator that runs both as a standalone full-screen aquarium game and as an interactive Android live wallpaper. Instead of scripted animations, the tank operates on live predator-prey AI and fluid hydrodynamics.

Players can inhabit their screen with either a Great White Shark or an agile Hammerhead Shark, each tuned with distinct turn radiuses and swimming momentum. Double-tapping the water spawns prey fish equipped with randomized IQ, schooling behaviors, and zig-zag evasion patterns. Feeding single fish lets you observe realistic stalking and jaw mechanics, while rapid feeding triggers Frenzy Mode, escalating the shark's attack speed and pursuit vectors.

Simulation Features:

- Dynamic Lighting: Real-time clock synchronization shifts the environment between daytime surface light and nocturnal deep-ocean ambiance.

- Foreground Inspection: Summon the shark directly to the camera glass to observe 3D fin articulation and bite physics.

- Full-Screen & Wallpaper Modes: Play in standalone aquarium mode with ambient underwater soundscapes, or run it on your Home and Lock screens at up to 120 FPS with zero ads and full offline support.
