Nuclear Testing Theory
Sponge-Bob Square Pants takes place in Bikini Bottom, a fictional undersea community located underneath a real-life isle called Bikini Atoll. Back in 1946, Bikini Atoll was used by the United States as a site for nuclear testing. Numerous bombs were set off there over the years; a particularly notable one called "Baker" was detonated 27 meters underwater. See Wikipedia's article on the island for more information. This theory states that Sponge-Bob and his friends are all so bizarre because they are the results of these nuclear tests.
The Seven Deadly Sins Theory
Although the theory was debunked by Tom Kenny in this HuffPost interview, it is possible that SpongeBob's friends represent the Seven Deadly Sins. There is some debate, but the best fits for each sin are as follows:
- Lust: SpongeBob. Lust is intense sexual desire. SpongeBob loves everything living or non living and everyone.
- Pride: Sandy. Pride is a deep satisfaction derived from one's own achievements. Sandy is deeply proud of her home country, her athletic abilities, and her career as a scientist.
- Greed: Mr. Krabs. Greed is the selfish desire for something, especially wealth or power. Krabs fits this sin perfectly, since he is obsessed with collecting money just so he can have riches for himself.
- Lust: Pearl. Lust is intense sexual desire. Pearl is depicted as boy-crazy and obsessed with male fish stars.
- Envy: Plankton. Envy is an insatiable desire. Plankton is deeply envious of the success that his rival Mr. Krabs has achieved.
- Gluttony: Mrs. Puff. Gluttony is the overindulgence of food. Mrs. Puff is shown to adore food, from chocolate cake to pasta, and is fat.
- Wrath: Squidward. Wrath is uncontrolled feelings of anger and hatred. Squidward hates his life, his job, his neighbors, and practically everything else about Bikini Bottom.
- Sloth: Patrick. Sloth is excessive laziness. Patrick is ridiculously lazy; he is unemployed, lives under a rock, and sleeps a lot.
It has been suggested that Patrick or Gary could also fit gluttony, since Patrick also loves eating a lot of food. Gary's food bowl is commonly seen, and the episode "Have You Seen This Snail?" features him running away after not being fed, but he is not fat like Mrs. Puff or Patrick. Also, his appetite is perfectly normal for a snail. Some fans think SpongeBob could fit lust since he is so loving, but he has been confirmed by Nickelodeon to represent positivity and optimism (opposites of sin), making it unlikely that he represents one of the seven sins. Additionally, his love for the world is genuine, not sexual.
Donut of Shame/The Secret Box Connection Theory
Below is a summary that connects the events of "The Secret Box" with "The Donut of Shame."
Patrick's birthday is near Christmas. SpongeBob set up a tea party for Patrick. When Patrick was at his birthday party, SpongeBob invited tons of friends until SpongeBob brought out a bottle of grog. Patrick and all the other guests chanted at SpongeBob to drink the entire bottle. SpongeBob started to feel dizzy. He danced on his table and prank called everyone else he knew. Patrick, unaware that his best friend was drunk, decided to take a photo of this moment. SpongeBob felt so dizzy that he said "A donut this nice could really make a guy happy!" before passing out. Patrick ordered another bottle of grog and drank the entire bottle just like his best friend and passed out on SpongeBob's kitchen ceiling. Later on, Patrick put the photo of SpongeBob in a box he calls "The Secret Box" So that is the picture we all wanted to know...
The Drug Theory
This theory states that five of the characters are each addicted to a different drug. There are several versions of this theory, popularized after a parody called "SpongeBong HempPants" was created.
- SpongeBob: Shrooms. SpongeBob has a wild imagination, similar to the mindset of someone tripping on shrooms. He can go from extreme happiness (good trip) to complete despair and fear (bad trip). He is also usually very happy as shrooms create euphoria.
- Mr. Krabs and Mrs. Puff: Medical cocaine. According to the this site, cocaine users can be irritable and paranoid. Mr. Krabs is very irritable when it comes to his riches and also paranoid about his formula being stolen. Mrs. Puff is irritable when she has to deal with SpongeBob and has almost PTSD-like bursts of paranoia about crashing a boat. Both of them are also very intense.
- Squidward: Medical heroin. According to the same site linked above, heroin abusers have many behavioral tendencies matching Squidward's traits. These include lying and other deceptive behaviors, bad performance in jobs, and avoided eye contact. Also, he is constantly moody and upset.
- Patrick: Medical marijuana. Patrick is usually laid-back, relaxed, and has a relatively positive outlook on life. He also eats a lot, as medical marijuana users experience a phenomenon known as "the munchies" after smoking it.
This theory also states that Sandy is against the others. As most viewers know, Sandy can get very annoyed when SpongeBob and Patrick visit her...because they are hyped up on drugs.
The Death Theory
This theory is a possible explanation for what many fans perceive as a negative change in Sponge-Bob's personality from the fourth season onwards. He is initially an intelligent and capable character who is rather naive, but he becomes increasingly stupid as the show progresses. This theory suggests that the old Sponge-Bob died during the 2004 film's famous death scene. Since sponges can asexually reproduce babies that are like clones, it is quite possible that Sponge-Bob was replaced by a baby of his, which is why Sponge-Bob's personality changes and why he never seems to age. It also explains why he is increasingly stupid: he is a child. But this was later to be disproved by Stephen Hillenburg who stated that season 4- present are all prequel episodes to the first 3 seasons and the first movie the 2nd movie is also a prequel. This explains why there are no mentions of Sponge-bob ever being manager or what happened after the first film.
