It is a starter kit for creating animated cartoon-style water in your 2D game. It comes with mobile-ready refractive (glass) shaders, water textures, an example of buoyancy physics, and a water collision FX with sounds.

The package includes two water refraction techniques:

1. GrabPass - the shader grabs and transforms what is directly under the water geometry. It is very easy to use and works fast on most platforms.

2. RenderTexture - the shader uses a texture rendered by a camera placed behind the water geometry. It can be optimised to give the best performance on mobile platforms.

The package also features:

+ 15 water materials (3 styles and 5 variants each),
+ 2 water types: a surface-animated one, and a plain refraction,
+ waves animated by the shader,
+ multiple parameters for customising the material and its animation,
+ a tool for easy material scaling,
+ 7 high-quality water collision sounds,
+ optional shader features (multi_compile),
+ 3 normal (bump) maps for refraction,
+ an example of Buoyancy Effector 2D physics,
+ underwater bubbles and water splash particle effects,
+ documentation.
