Doesn't Poser5/6 have toon kids in it? I believe there are, they aren't very detailed either... from what I recall. You might also consider the Daz eggbert and hatchling phoenix for the bird characters - if you're including any. I think ernyoka1 (TG) also has a toon bird available, real cute and would work well for what you're doing. Good luck and show us what you come up with finally. :)
