* AdaptationDisplacement: Movie? What movie?
** Subverted in a lot of cases, considering the movie was a popular summer blockbuster when it came out, and was frequently talked about on Nick prior to its release.
* BigLippedAlligatorMoment: This show might as well be called "Big Lipped Alligator Moment: the animated series".
* CrowningMusicOfAwesome:
** "You Broke My Heart So I Burned Down Your Farm"
** "Bionic Janitor"
** "Science Montage"
** "2StepN"
** "Hillbilly Holla"
** "You Gotta Move"
** "No Fear Bigfoot"
** The OminousLatinChanting in "Hypno-A-Go-Go" is bound to send chills down your spine.
* EarWorm: Bigfoot is 8 foot 10, He taught us to love again....
** "Well, you broke my heart, so I burned down your farm!"
* EnsembleDarkhorse: Bigfoot.
** and a random goat.
** Also, there's Freddy.
* MemeticMutation:
** The "Viewer Mail" and "Ask Dr. Pig" segments have become memes with the clips replacing various suspenseful moments from popular culture.
** MOOSESHARK
* HilariousInHindsight: When Music/WeirdAlYankovic guest stared in the episode "Get Bessy", the big twist was that he's actually a horse in disguise. He has since become a guest star on ''WesternAnimation/MyLittlePonyFriendshipIsMagic''.
* MoralEventHorizon:
** Baxter was an unlikeable little jerk to begin with, but he crosses this in "Puppy Love" where he plots to [[spoiler: marry Duke's sister, then [[NeverSayDie kick his family's various buckets]] to [[GoldDigger take his]] [[AssPull family's fortune of golden dog bones]]]].
** In "Pig Amok", Brunnhilda, Pig's [[ArrangedMarriage arranged wife]], is always seen berating and insulting Pig (who is too love struck to care) with no redeeming qualities to boot, but it's when she [[spoiler: laughs at Otis' supposed death by "broccoli poisoning"]] that you know she's over the line.
** Winky the ghost rabbit pretty much trying to fling the protagonists into {{Hell}} for exorcising his fellow ghost pets and declaring that if he can't have their bodies then [[HeroKiller they can't either]]. [[spoiler:Fortunately, Otis comes in to save the day]].
* MostAnnoyingSound: Dear GOD, Snotty Boy! Could you just shut up for five minutes?
* {{Narm}}:
** [[http://images.wikia.com/nickelodeon/images/8/86/Barnyard_DVD_%3D_Cowman_The_uddered_avenger.jpg The cover of ''"Cowman: The Uddered Avenger"'']]. Yes, we know it's a kid's show and it's obviously a spoof of a dramatic superhero comic book cover, but there's something so over-the-top corny about it that it hurts to look at it.
** In "Hypno-A-Go-Go", Otis panics when he [[ItMakesSenseInContext supposedly killed what was thought to be the farmer while under hypnosis]]. But his panicking sounds far too hilarious to be taken seriously. Since he considers the farmer his dear, dear friend (his words), one can't help but feel more seriousness and oomph should be put into it.
* {{Shipping}}: Otis and Abby.
* SuspiciouslySimilarSong: The title card theme for Hypno-A-Go-Go (which also plays throughout the episode) sounds rather similar to [[http://www.newgrounds.com/audio/listen/75028 The Graveyard(o)_(o)]].
* TearJerker: "Otis' Mom" features Bessy depressed because she lost her son when he was very young. It is also [[InMemoriam dedicated to]] Lee Paulsen, Creator/RobPaulsen's mother, who died during production.
** In "Dead Cow Walking", where Otis thinks he's dying and Pip gets real depressed over it.
** The scene in "Pig Amok", where Otis seems to have died. To add salt in the wound, Brunhilda even laughs at it.
** In "Tale of Two Snottys", where Nathan starts crying his eyes out and revealing his true feelings is just heartbreaking.
** Meta example: Creator/TinoInsana's (Pig's VA) passing on May 31, 2017.
* TheyWastedAPerfectlyGoodCharacter: Bingo said he was going to come back, but he never did. Would've made a good EvilCounterpart to Otis.
** Geraldo never tried to expose the animals again.
** Farmer Clem only returned in an episode towards the end of the series.
* TheyWastedAPerfectlyGoodPlot: Many fans were extremely disappointed about the show not depicting an episode where Dag returns to get his revenge on Otis, and therefore that story only exists in Fanfiction.
* UncannyValley: The animation of the TV series can be considered rather... odd. Especially when compared to the much more fluent animation of the film it was based on.
* TheWoobie:
** The farmer and Nathan.
** In some episodes of the series, Freddy counts as an IronWoobie. Particularly in "Meet The Ferrets" and "Fowl Play".
