History UrbanLegendOfZelda / Undertale

* The last and most bittersweet moment of the Pacifist ending, [[spoiler:Asriel's ultimate fate]], has had multiple rumors and methods spin around social media about how you can save him, these range from easy and sensible (saving the butterscotch pie and eating it near him), to the absurdly difficult like completing a NoDamageRun. None of these have been found to be true, there's nothing that can be done for him. [[note]]Saving the butterscotch pie for the end ''does'' trigger a unique response for ''Asgore'', who debuffs temporarily due to recognizing the pie, but does nothing special for ''Asriel''.[[/note]]

* It didn't even take an hour after Toby put out a 116 megabyte update to fix bugs before fans tore into the game's code looking for more stuff related to [[spoiler:Dr. Gaster]]. While nothing's been found as of yet ([[https://twitter.com/FwugRadiation/status/689817615150243842 and Toby made a post apologizing for no new content]], though that doesn't necessarily rule out [[spoiler:Gaster]] stuff), this one's fairly understandable because putting in content and hiding it as a bugfix is [[TrollingCreator definitely something Toby would do.]] [[spoiler:As it turns out, there is new dialogue regarding Sans' room and abandoning a No Mercy run on Papyrus, which [[ExactWords isn't new content, but a change to preexisting content.]]]]

* Naming your file "Chara" does not disable your ability to rename after a regular reset — you don't ''have'' that ability in the first place, unless you named your file "Frisk", and even that's only an ObviousRulePatch to prevent you from being stuck in Hard Mode.

* W.D. Gaster is an intentional nod to this trope, {{Glitch Entit|y}}ies and DummiedOut characters. Every reference to him in the game is only accessible by tampering with the game settings or through incredible luck, and together they paint a [[NightmareFuel disturbing picture]] of a brilliant scientist who was shattered through time and space by falling into one of his machines, erasing him so utterly that [[UnPerson it's like he never existed at all]]. Gaster seems intricately connected to the plot of the game - especially to [[spoiler:Sans, who just might be the one person who still remembers him]], but you would never know that if you didn't dig deep below the surface of the game. In short, his very existence seems to be tailor-made to incite fan speculation about his nature, his death and his role in the events of the game.

* When Sans gets serious and changes his font for one line, many fans believe the font in question is named "Sans Serif". Sans Serif is not a font, but a font ''family'', and all of Sans's speech is in a Sans Serif font. Hell, it's what the Sans in Comic Sans stands for.
** To be more specific, a [[https://en.wikipedia.org/wiki/Serif Serif]] is an extra line or stroke added to the main stroke that composes a letter, and "Sans" means "without". Times New Roman is a Serif font, Helvetica is a Sans Serif font.

* After completing the KillEmAll path, [[spoiler:the world is destroyed and you have to sell your SOUL to get it back]]. This caused many players to, somewhat logically, assume that completing it ''again'' would break the game irrevocably, since [[spoiler:you would no longer have a SOUL to sell]]. It doesn't, though; you just skip the required action entirely on subsequent runs.

* For whatever reason, Toby used real beta assets (old versions of Frisk's sprite and the Enemy Approaching track, as well as a probably-real battle screenshot of several Froggits, then called [=TestMonster=]) to make a joke post on starmen.net, claiming they were for the ''VideoGame/EarthBound'' ROMHack sequel to the subject of the thread... which was ''itself'' a nonexistent joke sequel to another hack. Those not familiar with the ''[=EarthBound=]'' hacking community failed to recognize the thread as a joke, and took the post as serious insight into the development process. Toby eventually went back and blanked said posts because so many people kept insisting they were legitimate.

''Undertale'' attracts a lot of this, due to its reputation for large amounts of DevelopersForesight.
