* {{Blooper}}: The text from the cutscene after clearing a castle only mentions Mario, even if the castle is cleared with Luigi. ''Super Mario Advance 2'' corrects this by mentioning both Mario and Luigi.
* CastingGag: Since Toad was left out of the animated series, production had John Stocker voice the replacement, Oogtar.
* DuelingGames: Everyone knows about the Mario-Sonic rivalry as the main front of the Nintendo-Sega UsefulNotes/ConsoleWars, but it was this game dueling with ''VideoGame/SonicTheHedgehog'' that was the focus.
* FanNickname:
** LetsPlay/{{Raocow}} has called Charging Chuck and Yoshi "Football Charlie" and "Stupid Horse", respectively.
** [[http://www.youtube.com/user/TheRealNinjaBoy TheRealNinjaBoy]] refers to Chargin' Chuck as any combination of the words "Mr. Charlie Man Jones."
** Website/GameFAQs' LUE board uses the very box image of the game as its god. They also call it [=LUEshi=], instead of Yoshi. They even have their own mod, if you're wondering.
** Fans of the cartoon have called Luigi "Emo Luigi" because of him crying in "Gopher Bash".
** The flashing, berserking shell created when a yellow koopa jumps into a koopa shell is typically called a "disco shell".
* GodNeverSaidThat: The 2017 interview with Takashi Tezuka and Shigefumi Hino never confirmed that Mario is punching Yoshi in the head. It confirmed that this was the [[WhatCouldHaveBeen original intention]], but also specifically confirmed that it was changed during development so that Mario is pointing instead. Unfortunately, misleading headlines reporting this interview resulted in CommonKnowledge that [[IKnewIt Mario punching Yoshi was indeed always the case]].
* IKnewIt: {{Subverted|Trope}}. Due to the way the [[https://am22.akamaized.net/tms/cnt/uploads/2017/09/Ylb1cK5.gif sprites looked]], a lot of fans assumed that Mario is punching Yoshi's head in order to make his tongue go out, rather than him simply pointing. In 2017, it was confirmed in an [[https://www.polygon.com/2017/9/28/16378812/super-mario-world-mario-punching-yoshi interview with the SMW devs]] that this was [[WhatCouldHaveBeen originally going be the case]]... but it was changed to pointing during development, so the assumption that Mario is punching Yoshi is still wrong.
* MarketBasedTitle: The Japanese packaging lists the game as ''Super Mario World: Super Mario Bros. 4'', but the subtitle was eliminated elsewhere (including its own home country).
* NewWorkRecycledGraphics: As pointed out by [[VideoGame/MegaMan8BitDeathmatch Geno]] on her [[http://geno2925.tumblr.com/post/166342128939/my-top-3-favourite-things-about-snes-era-mario Tumblr]], the graphic style of the game has been used in at least seven games, each using the same sprite for Mario, but at the same time using different front facing graphics for Yoshi, and different sprites altogether [[http://geno2925.tumblr.com/post/167165820649/why-are-there-so-many-bowsers-for-the-exact-same for Bowser]]
* ScrewedByTheNetwork: NBC gave this treatment to the cartoon's entire run. Viewers relying on word-of-mouth rather than commercials just to catch a new episode was the first straw. Being produced on a smaller budget than ''WesternAnimation/TheAdventuresOfSuperMarioBros3'', and thus limiting the episodes to one segment in each ''Captain N'' episode, instead of two with ''three'', was the second straw. The last straw, however, came when NBC halted production of the series without any prior announcement, then canceling it and its fellow NBC cartoons altogether as part of NBC's take-down of their Saturday morning block and replacement by teen-oriented TNBC. Its time slot was then occupied by local news.
* TropeCodifier: For EnemyRollCall.
* TropeNamer:
** For TheYoshi (now known as PowerupMount).
** The cartoon is the Trope Namer for IFellForHours.
* UnintentionalPeriodPiece: The cartoon ''is'' based on the game that launched the Super NES. It couldn't have come out in any year other than 1991.
* WhatCouldHaveBeen:
** The game was originally planned to have a lot more in common with ''VideoGame/SuperMarioBros3''. This included [[https://www.mariowiki.com/images/4/4f/BeatDinosaurLand.jpg Toad Houses in the overworld]] and items such as the [[https://www.mariowiki.com/images/9/95/Unused_Super_Mario_World_Sprites.gif Super Leaf]].
** According to a 2017 [[https://kotaku.com/confirmed-mario-was-originally-punching-yoshi-1818873540 interview with the game's developers]], Mario would have punched Yoshi on the head to make his tongue go out or to breathe fire. Most of the team agreed that this would be [[DesignatedHero too mean for Mario]], so they changed it to [[http://68.media.tumblr.com/tumblr_me1mruiMNO1rrftcdo2_500.jpg him simply pointing instead]].
