@JGoldman10,
Both cartoons you mention are incredibly surreal, you have given no indication that is what you’re trying to do.
Sandy Cheeks is counter stereotype, she’s a scientist.
In terms of characterisation Spongebob is more like a WW2 Buddy film where the Southern boy is one character along with the tough kid from the Bronx, the quiet religious type, the cowboy, the Ivy League scholar etc. than a something that focuses on then like The Beverley Hillbillies.
Why are you arguing about this? People have given you their opinion, and arguing about why they’re wrong isn’t going to get any work done.
