Mosasaurus Deep

An interactive mosasaurus ocean scene that replaces your new tab page.

Mosasaurus Deep replaces your new tab page with a living underwater scene. A mosasaurus follows your mouse and hunts, swimming with realistic sine-wave motion. It chases and eats small fish and baby megalodons that swim and flee across the screen, with bite animations and a running score. The scene includes an animated ocean background with drifting bubbles, swaying seaweed, and caustic light effects for a calm, immersive new tab experience. Built entirely with HTML5 Canvas and vanilla JavaScript — no external libraries, no tracking, no data collection.
