The Spongbob Squarepants Theory

Spongebob Squarepants is one of the most viewed kid's show because of its humor and,well,the story. Stephen Hillenburg,the creator of Spongebob,conceives it in 1984,while he was teaching marine biology. But he became an artist which is why he created Spongebob. But behind the fun and humorous Spongebob, there are many theories about it.
Here they are:

-All the characters are mutants because of radiation due to nuclear testing. It happened in Bikini Atoll which is most likely close to where the cartoon took place.Bikini Bottom.So it means that the radiation influence it due to the personalities of the characters.

-Spongebob and the other characters are reflected just like persons who are addicted to drugs.

-Spongebob is the always happy one going to being sad like crazy.
-Patrick is like a weed user which is dumb and dull who is always relaxed and lazy.
-Sandy is alcoholic, pertaining to his voice.
-Mister Krab is uppity and obsessed with money.
-Squidward is always annoyed and always screaming.
