Are you referring to "shaders" that you use in the material room?

There is a thread about "cartoons"  perhaps some information in there will help. There are links to some free shaders.

Also, if you go to the following link and enter the word "Toon", you can find cartoon type figures/props.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
