While browsing through toon style shaders on youtube, I came across this cartoon fluid test. I am pretty sure it is an emission shader, but I don't know exactly how to make it. This was originally made in Blender. I could not find any tutorials on it, so I came here. I just want to know the material; I can make the fluid simulation.

Answers with an image of the node setup would be highly appreciated. Thx!
