'''''Grossology''''' (2006-2009) is a cartoon series about a BrotherSisterTeam, Ty and Abby, who solve all the {{Squick}}-related problems in their town (within the confines of TV-Y7, of course). Based loosely on a series of books by the same name.

----
!!''Grossology'' provides examples of the following tropes:

* AdultsAreUseless, especially in Fartor's case. His older brother farted in his face every day for thirteen years until he mutated into a methane reliant fart monster. Why didn't his parents do anything all that time?
** PoliceAreUseless
* AlphaBitch: Paige Logan.
* AteTheSpoon: Pink-Eye's BlazingInfernoHellfireSauce eats a hole in the floorboards.
* TheBadGuyWins: Sort of. [[spoiler:Fartor, Insectiva and Sloppy Joe get happy endings near the end of season 2, but not at the expense of anyone else.]]
* BalloonBelly: Ty and Lab Rat in "Sloppy Joe To Go".
** Basso Profundo turns out to be just as skinny as he used to be, and the only reason he looked fat was because he had so much gas in him, which he lost over the course of his BurpingContest with Ty's and Abby's dad.
* BeardOfEvil: Lance Boil
* BeautyIsNeverTarnished: Averted so many times with Abby.
* BlazingInfernoHellfireSauce: Pink-Eye attempts to torture Lance Boil by force feeding 10 bottles of this stuff. It fails because Boil has replaced his stomach with an artificial digestive system.
* BlondesAreEvil: Paige and her sidegirls
* {{Bowdlerize}}: The French Canadian version of "Fartzilla" was heavily censored to remove flashbacks of Fartor getting farted on by his older brother as a child.
* BrotherSisterTeam
* BrownNote: Lance Boil uses one in "When You Gotta Go" to make everyone crap their pants.[[spoiler:Ty and Abby wear diapers that make them immune to its effects]].
* BurpingContest: Between Ty's and Abby's Dad and Basso Profundo
* TheCatfish: "Squirm"
* CompressedVice: In "Stinko" Lab Rat is suddenly a germophobe and bromidrophobe.
* CoolPet: Hermes
* CreepyChild: The Director's nephew in "Night of the Living Roadkill". He just stands there staring creepily and not talking.
* CutLexLuthorACheck: In "Sloppy Joe To Go" Sloppy Joe starts a successful fast food franchise, but all he cares about is creating more garbage for him to steal.
* {{Edutainment}}: The whole show
* EnemyMine: Abby and Insectiva once reluctantly teamed up against a carnivorous plant-themed villain.
* EvilAlbino: Sloppy Joe (when cleaned up).
* {{Expy}}: Any KimPossible fan might see Labrat as a taller, skinnier version of Wade.
** To say nothing of Abby as a junior-high version of Kim...who digs the gross stuff.
* FanGirl: Abby was VK's fan. So much a fan that she refused to believe that VK was the culprit despite seeming evidence. Only when VK admits everything does she get over her fangirl-ness and stop him good.
* {{Fartillery}}: Fartor
* FieryRedhead: Abby
* {{Flashback}}: In "New Recruits" Abby and Ty reminisce about how they first became Grossologists, as well as Lance Boil's origin.

* GrapplingHookPistol: One of the functions of the goop shooter.
* GrossOutShow
* [[HonestJohnsDealership Honest John's Dealership]]: Professor Skinner. Though he's more [[GeniusDitz inept]] than immoral.
* HowWeGotHere: Used in "Vertigo a Go-Go".
* ImprovisedParachute: In "Hirsute Yourself", Abby uses her giant beard (ItMakesSenseInContext) as a parachute.
* InMediasRes: The origin episode didn't come until season 2.
* ITakeOffenseToThatLastOne:
-->'''Paige:''' I came for a party and no creepy, weirdo, Goth loser is going to stop me!
-->'''Darko Crevasse:''' Oh, come on. I may be, as you say, 'creepy', but Goth? That's just insulting!
* IWasQuiteALooker: A flashback to Lance Boil's origin shows he was tall and handsome before he was mutated.
** Flashbacks to Insectiva's childhood show she was once quite adorable. And so was her sister, Arachnidia.
* TheLabRat
* LeeroyJenkins: Ty
* LimitedSocialCircle: Subverted. Ty and Abby don't seem to have friends of their own. In "The Perfect Stink", their parents [[LampshadeHanging point out]] how their kids never bring any of their classmates home. The only friends they've ever meet are Naomi, Andy and Lab Rat.
* LogoJoke: At the end of the credits the {{Nelvana}} logo gets [[CoveredInGunge covered in goop]].

* MayContainEvil: Sloppy Joe's fast food chain.

* MiracleGroMonster: Slitherbuddies from "Fangs A Lot".
** Both aired in Australia, but for unknown reasons the UK only got "Pucker Up".
* ModestyTowel: Abby and her mom wear these in "Spa Insectiva".
* {{Nephewism}}: In "Night of the Living Roadkill" the Director is shown to have a nephew. [[spoiler:Though since this episode turned out to be AllJustADream and he never shows up in any other episodes he might not really exist.]]
* NoCelebritiesWereHarmed: Darko Crevasse is based on Music/OzzyOsbourne.
* NoMrBondIExpectYouToDine: Inverted in one episode when Mrs. Archer invites Insectiva over for dinner, not realising she's a supervillain.
* TheNudifier: Kid Rot can dissolve anything organic with a single touch, including clothing.
* OfficialCouple: Sloppy Joe and Insectiva as of the Valentine's Day episode.
* OnlyKnownByTheirNickname: Paul "Lab Rat" Squirfenherder
* ThePigpen: Sloppy Joe
* PrecociousCrush: Abby had one on pre-mutation Lance Boil before he turned out to be evil.
* PrehensileHair: Freddy Folicle
* PrematurelyBald: Freddy Folicle's plot involved stealing people's hair, one of his victims of course being Abby.
* RapunzelHair Abby's hair is not only incredibly long, but very large and is often somewhat distracting.
* RedheadedHero: Abby
* RobotDog: Sniffer [=McGross=]
* RodentsOfUnusualSize: After being defeated and contained, Abby's evil part-rat clone turned from mostly-human-looking to a giant rat.
* RoguesGallery

* ThirdPersonPerson: VK, he doesn't even care if anyone finds it annoying.
* TomboyishPonytail: Abby

* TheVoiceless: Apart from some laughing and other sounds, Paige's friends don't talk.
* VomitDiscretionShot: Frequently.
** Speaking of, the lack of VomitIndiscretionShot in a GrossOutShow is, one assumes, a Y7-rating related issue. Which didn't stop the show doing an episode revolving around a puking spree (including Abbey puking for canonically the first time in her life), which made the Discretion thematically somewhat unfortunate.
* WalkingWasteland: Kid Rot
* WeirdnessCensor: When Abby was replaced by an evil part-rat clone of herself no-one noticed the fangs or pale skin.
