Why Is It So Difficult to Make Cute Characters?

1) well first i learned that a cartoon character is considered cute if it fits these standers

Head large in relation to the body.
Eyes spaced low on the head and usually wide and far apart.
Fat legs, short and tapering down into small feet for type.
Tummy bulges—looks well fed.
This is not surprising because these standards have been in place seance the start of cartoons.

2) secondly i learned there are some exceptions to this rule, like WALL-E. this makes seance because it wouldn't make any seance at all if everything did follow this rule.

3) lastly i learned that If a character is too cute and sugary sweet, the audience can develop skepticism. This is a good observation because if a character seems too nice then people will not relate to in and lose interest. 

Only question is why did someone wast there time thinking up all of this?
