Missing Cartoon Episodes!

 

• My Little Pony: Friendship Is Magic:
• In the Latin American dub, the 11th episode of the second season "Family Appreciation Day" was missing during Discovery Kids' premieres of other season 2 episodes. In fact, it didn't air until October 2013 (although it was made available on the Latin American Netflix a few weeks before it aired on Discovery Kids), after all of season 2 and Season 3 had premiered, and has been rarely re-aired for unknown reasons.
• A weird case of this trope is that the episodes "Luna Eclipsed," "Hearth's Warming Eve," "Scare Master," and "Hearthbreakers" are skipped when The Hub, and later Discovery Family, rerun the series, despite important world-building happening in the first two and character development in the latter two. This is because they are holiday episodes, so The Hub will only show them once at those times of the year (if they are shown at all), whereas every other episode will be shown repeatedly every month. (Oddly, "Hearts and Hooves Day" is not taken out of the rerun schedules despite it being a Valentine's Day episode and bearing far less importance to the series overall than either of the former two.)
• To a lesser extent, the Arabic and Turkish dubs skip the above mentioned episodes simply for being based on holidays that are considered un-Islamic. Many Turkish and Arab fans were not happy, as Luna Eclipsed features an important part of Luna's character development.
• The episode "Party Pooped" remains unaired on Canada's Treehouse TV network, most likely due to the title of the episode being inappropriate for the channel's preschooler demographic, much to the chagrin of Canada's bronies and pegasisters.
• Six clip shows were made during production of Season 9, where Starlight and Spike gather memories from Twilight's friends to make a memory book for her following her coronation as ruler of Equestria. Despite having aired in Australia in April and May 2020, and in Ukraine in July 2021, none of the clip shows have ever aired on Discovery Family in the U.S. or released anywhere else as of 2023.
• Regular Show:
• The first season episode "The Unicorns Have Got to Go" has never been shown in several Eastern and Central European countries, such as Poland, Hungary and Romania. The reason for its exclusion is unknown, though it likely has to do with the appearance of the unicorns, and Benson spraying water at Mordecai and Rigby to snap them out of their non-existent hangovers. It has also been rarely aired in the U.S., though the reasoning behind it could be because of the crude humor that was a little too [adult swim] for Cartoon Network (Mordecai drinking "unicorn slop," the unicorns pissing on the lawn, and the unicorns farting in Rigby's face). It was later included on The Complete First and Second Seasons DVD and Boomerang aired the episode uncut and uncensored.
• Likewise, the Halloween specials have also been ignored in those regions, up until the 2014 Halloween season.
• "Go Viral" never aired in Australia for unknown reasons (the episode really isn't any worse than episodes that did air over there, though it may have been because a lot of the behavior in the episode was imitable).
• For unknown reasons, the Region 4 release of Season 4 is missing the episode "That's My Television".
• Sponge Bob Square Pants:
• The first episode, "Help Wanted", was not included on the Season 1 DVD release due to the use of the song "Livin' in the Sunlight, Lovin' in the Moonlight" by Tiny Tim. Later DVD releases included it.
• "Goo Goo Gas", a season five episode, didn't air in the USA until 9 months after the rest of the season (it aired on July 19, 2009). This is possibly because its partner episode "Le Big Switch" didn't air much because of Nick being paranoid over "gay" stuff. It was however aired in multiple countries before the US and released on DVD before its US airdate.
• The episode "SpongeBob, You're Fired" has not aired on Nickelodeon since 2015, allegedly because SpongeBob creator Stephen Hillenburg despised the episode and asked Nickelodeon to pull it when he returned to the series. However, the episode also came under controversy around its air date as it dealt with the topic of cost-cutting employee benefits And the practice in a humorous light. There's also the matter of a questionable scene where Krusty Krab competitor Mr. Weiner gets run over by a bus while walking down a road, which for a children's program is quite taboo. As of 2018, Nickelodeon has since restored the episode in rotation, although it airs rarely (It only airs when Nick airs SpongeBob specials in hype of a big event in Nick's schedule).
• "The Sponge Who Could Fly", also known as the "Lost Episode", parodies this, and actually did an okay job of being a seemingly real example of lost media, thanks to the episode only airing once every few years.  However, it is available on the Season 3 DVD boxset, and since 2013 airs regularly on Nickelodeon and Nicktoons.
• According to the official SpongeBob SquarePants Wiki's list of deleted scenes :
  • The season two episode "Wormy" (aired in the US on February 25, 2001) was banned in some countries due to the scary close-ups of the buzzing horsefly being quite frightening to younger viewers.
  • Another season five episode, "The Two Faces of Squidward", was banned in a few countries due to two reasons: 1. Both "handsome" Squidwards (especially the second one that became Memetic Mutation) really frightened younger viewers, and 2. The constant hitting Squidward in the face with a door, which a lot of countries don't tolerate, and is against the standards of several countries' rules for children's programming. 
• Spongebob Rehydrated, an All-CGI Cartoon parodying the second Matrix film, is considered lost by fans. Footage of the entire short was eventually found, although the original audio remains missing.
• Astrology with Squidward was a series of Nickelodeon Shorts and Interstitials that aired circa 2000-2001 where Squidward explained the zodiac. Nick stopped airing them in 2005 and there were believed to be a few missing shorts due to the fact that not every astrological sign was covered  . Nick eventually uploaded them onto YouTube and Vincent Waller has since stated that no other shorts were made besides the ones already posted online.
• "The Kwaratined Krab" was left unaired in the USA after the COVID-19 pandemic because of the plot being about the Krusty Krab going under quarantine (though it did air in several other countries including Canada where it was even available on demand). Not even the Complete Twelfth Season DVD coming in January 2021 will include this episode, leaving its sister segment "Who R Zoo?" alone on disc 3 (though "Hiccup Plague", which was also unaired for the same reason, was on the disc). Though the episode was finally aired in the USA in April 2022 (along with the aforementioned "Hiccup Plague").
• "Mid-Life Crustacean" was removed from rotation in 2021 due to its final scene centering around a "panty raid", the act of stealing women's underwear (though it can still be purchased on YouTube and iTunes) , this plot element was deemed to risqué for a children's show.
• Both "Shanghaied" and "Gary Takes a Bath" which were paired together, were banned for a long time in the United Kingdom and have aired there only rarely. The former was banned due to the disturbing nature of the Fly of Despair scene, while the latter was banned due to an inappropriate "don't drop the soap" Adult joke and the somewhat frightening "subliminal messages" girl.

The Dutch Nickelodeon website at one point in the 2010's had the first part of The Jimmy Timmy Power Hour 2: When Nerds Collide available, but the second part was nowhere to be found. What's interesting is that it remained available until long after Jimmy Neutron had stopped airing on Nickelodeon in the Netherlands

• The ChalkZone episode "The Smooch" is missing from the show's complete series DVD set on Amazon due to music rights. The Baha Men's cover of "Coconut" was prominently featured at the end of the episode, and it was too important to mute/edit out. The DVD contains the other episode and the music video it was paired up with originally ("Power Play" and "All The Way to The Top") at least; the iTunes episode collections didn't include any part of the half hour at all. The full episode did remain in the show's rerun rotation until 2013 (when Nicktoons took ChalkZone off the schedule).

• The Fairly OddParents! has "Twistory" and "It's a Wishful Life", both of which are also Canon Discontinuity (though they still air on Nicktoons to this day).
• "Twistory" was pulled from reruns due to the fact that it offended both Americans and British while trying to be patriotic and also said that if American independence never happened, then the world wouldn't have advanced past the 18th century.
• "It's a Wishful Life" aired in reruns for a few years, but was eventually pulled from TV due to both negative reception.
• "Where's the Wand?", an episode from back when the show consisted of Oh Yeah! Cartoons shorts, has never aired again after The Fairly OddParents! become a full-fledged cartoon. It was released as a bonus feature on the DVD of School's Out! The Musical.
• Back when the show still aired premieres on Nickelodeon, Nicktoons would only air reruns of the earliest episodes. This also happened with Sponge Bob Square Pants. This problem has been fixed with The Fairly OddParentssince the 2014 rebrand and SpongeBob since 2016.

• Animaniacs (2020) had the sixth episode removed due to flashing lights in "The Cuteining" and the phone number used in "Close Encounters of the Worst Kind" being already in use... by a Adult phone hotline. The episode was reinstated shortly afterward without the phone number before the number changed to a different one.
  • When Teletoon aired the show, episodes 11 and 12 were skipped. It's understandable for the former as they probably did not want to air an Out of Holiday Episode (as that episode was a Halloween Episode), but there's no explanation on why episode 12 was skipped.
• When The Loud House is aired in Italy on Super! TV, each of the first three seasons have an episode that is removed from rotation after a few reruns: "Toads and Tiaras/Two Boys and a Baby" for Season 1, "11 Louds a Leapin'" for Season 2 and "Deal Me Out/Friendzy" for Season 3. The reasons for those removals are unknown, though the second is understandable as it's a Christmas Episode, which typically don't air year-round

Arthur:

• The 2002 special "Arthur, It's Only Rock and Roll" hasn't aired in reruns on television, likely to avoid confusing children as it features theBackstreet Boys. It was released on DVD, and was also available to stream on Amazon, but was eventually removed, possibly to the expiration of rights to the band's music featured throughout. However, it did air as part of an Arthur marathon on the PBS Kids channel in February of 2022 held to promote the final episodes of the series.
• After the 2012 revelation that Lance Armstrong cheated throughout his career by doping, three episode pairs that feature either Armstrong himself, or a parody of his likeness, were pulled from reruns, though they are still available on iTunes, Amazon, and YouTube Premium. These episodes are:
• Season 10: "Binky vs. Binky/Operation: D.W.!"
• Season 12: "Room to Ride/The Fresnky Family Fiasco"
• Season 13: "The Great MacGrady"
• In addition to the three episodes mentioned above, the Arthur marathon on the PBS Kids channel from February 16, 2022 to February 21, 2022 skipped the following episodes:
• The specials "Arthur's Perfect Christmas", "Arthur and the Haunted Treehouse" and "An Arthur Thanksgiving" were skipped because airing them outside of their respective holidays would make little sense.
• "It's A No-Brainer/The Shore Thing" was skipped because of a brief joke about a noose in one segment.
• "Arthur Weighs In/The Law Of The Jungle Gym" was skipped because of the use of the words "fat" and "fatty" throughout the first segment.
• The Arthur's Missing Pal movie was skipped because the rights to the movie are owned by Lionsgate.
•
