Yes, the show is about lots of gross things, so you can expect it to come into this territory.
- Queen for a Day: The very idea of giant, mutated termites might freak out viewers with insectiphobia.
- The Slim Slime Man: It starts out with a nice scenery of people in the park. Nothing wrong here. But then we go down to the sewers where Slim is seen bitterly scraping slime but then, said slime comes alive and attacks poor screaming Slim as the scene cuts to the opening.
- Slim's transformation into said Monster of the Week is nothing short of Body Horror. Though it mostly happened offscreen, the end result has him turned into a large glob of slime with a ghoulish skull who wants to cover the world in slime.
- Thankfully he gets better at the end of the episode and even reforms but how he's defeated can still be considered this, especially If you don't like spiders or snails.
- Fartzilla: Lary's whole situation that caused him to become a villain: Getting constantly tortured by his older brother via Dutch Oven method, until he got used to breathing said fumes- and now clean air is toxic for him.
- Some Fridge Horror while we're at it: Why didn't their parents do anything to stop this?!
- His plan is to use his so called "Fartzilla" to dutch oven his brother but considering the size of said robot, if the smell didn't kill him, he probably would have been killed via crushing.
- Also after he leaves the Archer siblings in the lair, it floods with "Flatchup" which acts like quicksand and nearly drowns them. Granted they escape but still.
- The Perfect Stink: The idea of smelling so bad, people can't help but pass out when smelling the stench can come off as this.
- The Scab Fairy: The titular villianess can come off as this what with her constant mood swings.
- When Ya Gotta Go: A sonic ray that gives people instant diarrhea is sure to bring up some Paranoia Fuel.
- Imagine it from the victims' perspective: a small man aims a violin-case at you. That seems weird enough- except suddenly, your own bowels go out of control and you don't even know why.
- Club Parasites: Mass Brainwashing + Mutated Head Lice. Enough said.
- Go Fish: This episode's Monster of the Week is a group of mutated Hagfish (otherwise known as slime eels). Let's begin the education:
- First, let's take a biology lesson: Hagfish are slimy scavenger eels with no eyesight, no sense of hearing but a good sense of smell and one huge gaping mouth full of sharp teeth. Sounds wrong enough already? Now imagine if they were mutated to grow even bigger (WAY bigger) than your average eel in real life and are out to eat ANYTHING that gets in their way. You get this episode's monster.
- These things are also capable of roaring and it is not a good sound to hear.
- When our duo encounter these things, they try to disguise themselves by camouflaging their scents with more rotten food and sludge. Sure, it was a good plan except, said Nasalflage actually attracted them even more. Oh, and to make matters worse, the rotten food jammed their Goop Shooters, forcing our heroes to run while screaming in terror all the while.
- To add on to that, said slime eels manage to corner the duo in a empty vat and nearly fill it to the brim with their own slime nearly drowning the Archer siblings. Thankfully they got out okay, but still there's a really good chance that they almost drowned.
- Reaching the episode's climax, the Archer duo manage to corner the Hagfish at the pier and give them an all out slime attack and it looks like victory, but then the slime doesn't work and the horrid eels look even madder then ever. But it gets better when we realize that these monsters are no match for the power of kittens!
- Its Gotta Be The Shoes: the episode's villain's lengths to stay famous, which includes giving everyone a painful foot disease. Also borders on Paranoia Fuel.
- Not to mention his high powered basketball and what it would do in real life.
- Owl Most Fowl: One villain of the week takes "four and twenty blackbirds baked in a pie" literally by putting pigeons in a pie on a Conveyor Belt of Doom that leads into a giant oven.
- The cold opening is no slouch either. We see Lab Rat and Hermes on a night stroll when suddenly, a giant robotic owl comes out of nowhere and nearly captures Hermes. This event managed to scare Lab-Rat into staying in the bathroom for a majority of the episode. Fortunately, he gets better by the end.
- Yack Attack: The idea of getting poisoned by the water you drink. It affected almost everybody including the Queen of Squeam herself!
- Kid Rot: Chester's situation is this. He only wanted to make the world a better place, only to get his rotting touch power and it seems that he can't control his other personality. It doesn't help that the episode has an ambiguous ending.Abby: Poor Chester.Ty: Poor Chester? Kid Rot is on the loose. Poor us.
- The Insider: Lance's plan involved Brainwashing Ty from the inside out. To clarify, he shrinks himself down to microscopic size and begins to mess with his body and Ty is powerless to stop him.
- While trying to save her brother, Abby is nearly killed multiple times due to white blood cells confusing her for a virus.
- All Together Now: One of the worst possible situations the Grossologists have faced. Besides the fact they were bombarded with halitosis giving horseflies, acne and garbage water which is somewhat scary. No, what's really scary is the fact these deeds are what got the bureau of Grossology temporarily closed down leaving the agents without their gear to fight three dangerous, disgusting villains on their own.
- Heck, the fact that Lance managed to hack the Gag Lab despite being fired shows to them that he is still a threat.
- Oldie But a Goodie: Abby's situation. After getting covered in some strange pus, she starts to age at a quick rate and nearly becomes an old lady near the episode's climax.
- Survival of the Grossest: What happens when toxic waste meets horseflies that reproduces at a crazy rate? You get giant mutant houseflies causing destruction wherever they go.
- School's Grossed Out For Summer: A procologist (a scientist who studies human digestion) transforms the whole school into an enviroment, which is rather reminescent of a human's own digestive tract.
- Can you even imagine it? One minute you're inside a seemingly normal school, and the next minute there is lots of reddish-pink flesh covering the school walls and tiles, a lot of rumbling digestive noises from beyond, plus there is no possible way out of this twisting maze. Plus there is a lot of gastric juices, and we all know what gastric juices does to the human-body.
- Vein Drain: the fact the episode revolves around leeches.
- Silent But Deadly: Far-Ty was also pretty creepy, especially since the brainwashing on Ty worked so well; him helping take Abby hostage and her desperation to get her little brother back doesn't help matters.
- The King of Rottingham Forest: Kid Rot's back and crazier than ever!
- The scene where he summons a huge wave of rot to destroy a forest and the summer camp full of kids.
- Lights Out: On an effort to catch Darko Crevase via car chase, the GRS-1 is bombarded by bat guano causing the Archer siblings to nearly crash.
- Heck, Darko can also come off as this with his ability to control bats and his obsession with darkness.
- A New Leaf: Giant.. Man-Eating.. Plants!
- You Heave, You Leave: The prop stomach filled with real acid.
- Sinister Romance: You thought Insectiva was bad, you haven't met her arachnid-loving sister: Arachnidia!
- Said sibling rivalry involves summoning giant legions of insects and arachnids to terrorize the city.
- Vertigo a Go Go: The idea of getting brainwashed via vertigo causing nanobots can bring up some scary thoughts...
- Not to mention Abby is fully aware of what Lance is forcing her to do, up to and including attacking her little brother. It doesn't help that during their fight, she's actively begging him to fight back since that's their only chance of stopping Lance.
- Mold Monster: Roger almost dies from black mold exposure. Even worse is that you can actually see him become paler and more ragged-looking as the episode progresses.
- Pinkeye's Revenge: Abby being replaced by the rat-clone was kinda disturbing, especially since her captor was an adult male- plus it's clear that she's powerless to escape for a good while. Plus the rat-clone itself was pretty creepy.
