** [[spoiler:As demonstrated in the song "Undertale", there were already golden flowers in the Underground, whereas in the game, they only started appearing there after Toriel left Asgore.]]

* InMemoriam: "Evacuate" has a credits dedication to Moony, the artist who made the artwork for all the pacifist songs and the genocide one until "Evacuate"

* BassoProfundo:
** Asgore. He hits an A in the C1 Octave in the opening for "Bergentrückung".
** Steel (Sans) hits some very low notes in parts of "Megalovania."

It's followed up by ''VideoGame/{{Deltarune}} the (not) Musical''[[note]]Also known in the thumbnails as ''Deltarune the (songs similar to a) Musical''[[/note]], a series of songs based off of the soundtrack of Undertale's successor, which can be found [[https://www.youtube.com/playlist?list=PLU-TFjG0qugBTkOsEte4fXdze1KwiBPu_ here]]. Similar to the Genocide package, there is no dialogue between the Deltarune songs, and, like the title says, they're not part of a full musical. Despite a longtime refusal to cover fanmade content (a few songs from the Genocide package nonwithstanding), covers of ''VideoGame/UndertaleYellow'' also started in 2024, once again not as a full musical.

All of the musical's songs can be found [[https://www.youtube.com/watch?v=99g8k_LAhi0&list=PLU-TFjG0qugDOnndeSWGpQ_BTmzEBlK09 here.]] The full musical as one video was livestreamed on Website/YouTube and can be found [[https://www.youtube.com/watch?v=opUb5hdzRRApc here.]] Man on the Internet has also made videos for a Genocide package (but not a full musical, as it doesn't contain dialogue between songs), which can be found [[https://www.youtube.com/watch?v=X7BsEsGj1BY here.]] It's followed up by ''VideoGame/{{Deltarune}} the (not) Musical''[[note]]Also known in the thumbnails as ''Deltarune the (songs similar to a) Musical''[[/note]], a series of songs based off of the soundtrack of Undertale's successor, which can be found [[https://www.youtube.com/playlist?list=PLU-TFjG0qugBTkOsEte4fXdze1KwiBPu_ here]].

* AdaptationalPersonalityChange: [[spoiler:In the Genocide Pack, Sans makes MUCH clearer just how much pain the Fallen has caused him with their actions, screaming and forcing out his lyrics for "Megalovania" as if he's suffering a complete meltdown. This was a conscious decision on the part of the musical's actors and developers.]]

* AdaptationalAlternateEnding: The Genocide Package has a bonus episode "Entry Number 17 - Dark Darker Yet Darker" that ends with [[spoiler: W.D. Gaster erasing Frisk and saving the world rather than merely having the world be destroyed by Chara]].

* AdaptationalJerkass: [[DownplayedTrope Downplayed]]. Papyrus is still the KindheartedSimpleton he is in the games, but he is a tad quicker to lose his temper [[spoiler: with both Sans and the Royal Guard, repeatedly shouting at the former to stop messing with his music and impatiently dismissing the latter as "amateurs" when they fail to capture Frisk.]]

* TakeThat: [[https://www.youtube.com/watch?v=O2xYAj42sqs Underfell the Musical]]. [[spoiler:Literally the entire video is an abridged retelling of the play but with all vocals turned down, the color pallet resembling something out of a UsefulNotes/VirtualBoy game, and shoehorning Megalovania at the end at where the Judgement Hall scene would be.]] The description says it all:

* AdaptationalJerkass: [[DownplayedTrope Downplayed]], but Papyrus and Sans throw a few more strays at each other here than in the game.

* AdaptationalPersonalityChange: [[spoiler:In the Genocide Pack, Sans makes MUCH clearer just how much pain the Human has caused him with their actions, screaming and forcing out his lyrics for "Megalovania" as if he's suffering a complete meltdown. This was a conscious decision on the part of the musical's actors and developers.]]

* LyricalDissonance: The background music for most of Flowey's songs sound like they belong in a children's TV Show. The lyrics most certainly do not.

** One of the lines during "Metal Crusher" is [[Music/Madonna "I've got style, I've got grace, now get out of my face!"]].

** One of the lines during "Metal Crusher" is [[Videogame/DonkeyKong64 "I've got style, I've got grace, now get out of my face!"]].

** More explicitly the case with Chara-their song "Star" is basically them lamenting their original life before saying that they have accepted that all they can do now is embrace [[OmnicidalManiac what they've become]].
