[[caption-width-right:300:Even the bags under his eyes have bags.]]
Let's face it. ''[[WesternAnimation/SpongeBobSquarePants SpongeBob SquarePants]]'' has ''[[GrossOutShow a lot]]'' of disgusting scenes, particularly in the episodes [[SeasonalRot after the movie,]] though by no means limited to them.
* "Fear of a Krabby Patty" has a scene in which Squidward tells Mr. Krabs he has to go home because he's SO tired, the bags under his eyes have bags under the bags. Cue a GrossUpCloseUp with a woman shrieking rather appropriately in the background.
* "SB-129": Squidward ends up in prehistoric Bikini Bottom and comes across Spongegar and Patar. Patar greets Squidward with a GrossUpCloseUp of his mangy grin, bearing teeth and gums and exuding halitosis.
* "The Splinter": [=SpongeBob=] gets a splinter at work. Rather than making the best of this sure-to-be-disgusting plot and having him try to get it out in a silly fashion, we're treated to 11 minutes of it getting infected, swelling, and oozing pus all over the place until Krabs walks up and pulls it out, thus causing gallons and gallons of puke green pus to shoot out and cover everyone.
* In "Plankton's Regular", [=SpongeBob=] (via getting pushed under a door) and Plankton (via force-pulling) both are ''peeled'', quite disgustingly.
* In "House Fancy", Squidward '''loses a toenail''' in the grossest way he can. Squidward gets the leg of a couch on his toe, and it's ripped off by [=SpongeBob=] pulling the couch away too soon. It had blood and veins still attached, even. To make it all worse, ''Squidward slips on the bloody nail''. You want to see it? [[http://www.youtube.com/watch?v=yojDSv25aak Here you go.]] [[ShmuckBait Have fun.]]
* "To Love a Patty", [=SpongeBob=] falls in love with a Krabby Patty, keeps it around until it's moldy, fungus-covered and ''maggoty'', then ''eats it''. It had maggots, worms, blue and black mold, highly detailed rotten meat, and an assortment of other disgusting things that you could imagine [[GrossUpCloseUp painted with incredibly uneeded detail]]. [[http://www.dvdtalk.com/reviews/images/reviews/190/1188867804_4.jpg See for yourself]] A similar plot had Krabs not wanting to dump a moldy patty so he can make money off of it. Apparently hospital visits cost less than a patty.

* The episode where [=SpongeBob=] adopts a worm and it has babies, which he then tries to get other people to adopt. Normally worms are fine in the series, but for this episode? They purposely made them incredibly disgusting. It was horrible.
* An episode featured Patrick tearing the entire front half of his skin off, revealing his bones and organs underneath, after a misunderstanding; [=SpongeBob=] [[LampshadeHanging looks suitably grossed out]]. It's kind of tame compared to most of the examples in this list (and ''definitely'' tame compared to "The Splinter"), but it could still cause instant gag reflexes in some.
* "[=SquidBob=] Tentaclepants": [=SpongeBob=] and Squidward were accidentely fused togther. Most of it wasn't so bad, but at the very end, when they were finally separated and Squidward wanted to be fused together again for personal gains, he accidently caused not just [=SpongeBob=] but several other characters ''to be [[BodyHorror fused together as one huge fleshy blob]]! ''''Uggghhh''.... and this is a ''kid's show'' for crying out loud!
** This scene was actually cut out in some countries, leaving the episode with NoEnding.
* "The Donut of Shame". Patrick gets a donut he believes is [=SpongeBob=]'s but keeps wondering if he should eat it or not. So throughtout the episode, he does a lot of things including placing it in a couch, a toaster, a toilet, and his own butt (seriously). Then twice he eats it and pukes it back up. At the end of the episode, [=SpongeBob=] EATS it. [[LampshadeHanging If you look closely, you can see [=SpongeBob=]'s look of horror as he "savors" the donut.]]
* [=SpongeBob=] -- as ''a fetus'' -- eating a Krabby Patty -- through his ''umbilical cord -- in his mom's womb in "Truth or Square". The notion isn't particularly bad... it's the presentation. The Krabby Patty travels through the umbilical cord, and it's pretty straight-forward, until [=SpongeBob=] rips the umbilical cord out of his abdomen and puts it in his mouth to suck it like a straw!
* "Pineapple Fever" has Squidward rip his own eyebrow (WITH the skin) off after [=SpongeBob=] makes a loud noise.
* The episode where Krabs and Plankton compete by selling more greasy items (including "soup" which is just grease on a plate).
* [=SpongeBob=] [[EyeScream steps directly into the eyes of the Tattletale Strangler, embedding his feet up to the ankles, while also wearing cleated shoes]].
* The episode where Plankton hides out in a machine designed to look like a milkshake, and is then drank by a fish. Guess how he gets out.
* An episode had Squidward giving Mr. Krabs a massage, and lowers his shirt to find it full of barnacles with insects crawling over it.
* Patrick eating a rancid piece of Krabby Patty ''that was in his belly button''.
* The Plankton Show has a lot of these but a list would be too long.
* "For Here or to Go" has Plankton winning a Krabby Patty after a seed counting contest. Most of it wasn't so bad until the end. He has to eat it and digest in the restaurant, and then he goes to the Chum Bucket for Karen to ''use a sawblade to get it out of his system''. The worst part? [[AndIMustScream NO ANESTHETICS]]! At least it was offscreen.
** After that, Karen "jokingly" puts Plankton's body fluids in his Krabby Patties. We even get a GrossUpCloseUp of the bag it's in!
* The scene of Spongebob cutting the huge zit off of his nose with a large pair of scissors in season 2's "Krusty Krab Training Video." Just.... Deeaaugh.
* In "Free Samples", after eating a Krabby Patty, two fishes' heads ''morph into hands that high five each other.''
* In "Eek, an Urchin!", the urchin lands in the Krusty Krab dining area. The customers, completely oblivious to the urchin, proceed to choke on and ''eat'' it.
* "Shell Shocked" brings us a [[SarcasmMode delightful]] [[GrossUpCloseUp close up]] of SpongeBob's gruesomely hurt face after he whacks it with [[ItMakesSenseInContext a tennis racket]].
* ''All'' of the "funny" faces in "Face Freeze!".
* In "Giant Squidward", Squidward is forced to have a bunch of boy scouts sleep under his toenails. It's pretty tame compared to most of the examples of this page, but it's still pretty gross in context.
* The entirety of "The Gift of Gum". Basically, Patrick gives [=SpongeBob=] a gigantic ball of used gum. It's as disgusting as you would think.
* Brain Gary from "The Inside Job".
** Which is [[LampshadeHanging lampshaded]] by Plankton immediately afterwards.
-->'''Plankton''': That's disgusting!
* In "Suction Cup Symphony", Patrick breaks his bones in his butt and it causes them to be visible outside. So he pushes them back inside, and briefly you can ''see the bones inside his mouth''. Uggghhh...
* In "Mermaid Man and Barnacle Boy IV", the shrunken residents of Bikini Bottom enter Spongebob's body, via his pores, and continue to attack his innards, most notably, Squidward [[UpToEleven taking a saw to a vein]].
* In "Plankton's Pet", a fish picks up a piece of gum from his shoe and then '''''eats it!''''' Apparently, [[WhatAnIdiot that guy is oblivious]] to the fact that there could be over ''a million'' germs [[TooDumbToLive that could make him sick]] on that piece of gum.
* In "Squid Baby", where Spongebob had to change Squidward's dirty diaper. We even get [[GrossUpCloseUp close-ups of the dirty diaper]]. Soon after Squidward bumps his head in the ice machine he is back to normal. He discovers he is wearing a dirty diaper (even a "fart" is heard when he opens up the diaper). It's just disturbing.
