well, i feel much better knowing that i'm not the only one wasting brain cells by wondering why that is.
in my own quest, i reached another conclusion: thumbs are a must, but it isn't really anatomically necessarily to have five fingers.
i've also noticed that [/I]most characters[/I] get hands: pigs, cats, sponges, dogs, mice, coyotes and ducks. some do not, like horses and roadrunners.
i also want to know why they are half-dressed many times: daisy duck and minnie mouse wear their dresses too short and male characters wear jackets often, but no pants.
