My favorite kids have to be john and roxy. John contrasts well against a lot of the other characters, and stands well on his own. I enjoy that he is not argumentative and is genuinely a good person :] I enjoy roxy because she is an awesome girl who loves the color pink, cats, and science which I enjoy myself.
I also enjoy dad and mom.
