In conclusion, I have found that the characters of Spongebob Squarepants function at various levels of moral development, with Sandy being at the highest level of all the characters. Most of the characters are only at the first stage, but that may also help with the show's humor. The show generally does not try to send any sort of moral message, so the moral development of the characters is not a priority of the shows creators and writers.
The show has great appeal to viewers of all ages through its varying levels of humor and sophisticated animation. No wonder it has become such a huge presence in American kids' culture.
