Animated Theme I want to go with and Drawings

I really like the Snoopy character animations / idea of being animated. How it is like a drawen image being ontop of the background. Having the idea of simple and clear colours where simple linings are there which make us know what area or place they are in.

A clear example in a video I would like to try to do is the starting of the beginning cartoon and middle part.
