Most timelines: Sans figures out a loophole in some tax forms.

Flowey Run: Flowey pushes Undyne and Alphys closer together through deliberate acts of villainy.

Post-Pacifist: Using a human skeleton model, Flowey tries to trick Sans into thinking he'd beaten Papyrus almost to death. Sans immediately dismisses it...because the model skeleton doesn't have clothes and Papyrus would never go naked.

Most timelines: Flowey asks Frisk is they want to see him naked. Frisk freaks out...but all Flowey does is lift himself out of the ground and expose his roots while laughing at Frisk.

Post-Pacifist: After his ill-fated visit to the human village, Asriel became known as a cryptid.

Post-Pacifist: Flowey learns he, in his former life as Asriel, became known as a local cryptid to the residents of the nearby human village. He decides to exploit this...

Most timelines: Sans gets drunk and takes boosting his brother to an extreme degree.

Most timelines: Sans pays his tab....by putting cash in a can of Tab cola.

Post-Pacifist/AU: Frisk relates to Undyne a dream of their teeth falling out. Undyne tells them it's no big deal, since teeth just regrow whenever one bites something too hard.

Post-Pacifist/AU: To demonstrate that there's nothing to be worried about when it comes to losing teeth, Undyne yanks out one of her own teeth, which grows back instantly.

Most timelines: Caught eating off a tree like a dinosaur, Alphys excuses herself by saying it tastes better that way.

AU: Undyne stops the genocidal human, but unfortunately becomes an amalgamate afterward with Alphys. Mettaton finds the resulting amalgamate difficult to work with.

Asriel and Chara Time/AU: Chara, as a SOUL absorbed by Asriel, keeps complimenting their monster body. Asriel is embarrassed.

Post-Pacifist: On account of the whole “humans can easily kill monsters with cruel intentions” thing, monsters get very nervous around human doctors/surgeons...

Post-Pacifist: A failed author of a very detailed manual on how to make potato chips throws thousands of copies of the book into the local dump. Decades later, monsters thank the author for providing knowledge on how to make popato chisps.

Post-Pacifist: Improbably, a human recognizes Catty’s overalls are the very same overalls the human used to wear.

Pre-Frisk: On his TV show(s), Mettaton makes a (heavily fictionalized) episode on the fallen humans, and how they were killed. Asgore sees it and cries. (inspired by Magic Fandoms)

Post-Pacifist: Frisk asks Asgore to protect them from some bullying kids. Asgore’s words/behavior upon hearing this suggests him plus violence to children is a bad combination. (inspired by Magic Fandoms)

Post-Pacifist: Cemetery employees see Asgore sobbing at a child's grave. He must very carefully explain himself to the cemetery employees...(inspired by Magic Fandoms)

AU: Crackfic in which Asgore disassociates himself into a “dad” and “king” persona, and literally blames his crown for killing/ordering the deaths of humans. (inspired by Magic Fandoms)

AU: Frisk goes back in time to prevent Asriel from ever dying. Improbably, the day Asriel and Chara died is a holiday that happens to be a prime day for dating, so none of the main characters exist now.

Flowey Run/AU: Flowey, “following [Chara's] footsteps”, decides to eat a bunch of buttercups. It takes eating an entire field of buttercups until he realizes flowers can't get poisoned by eating other flowers.

Flowey Run/AU: After eating an entire field of buttercups, Flowey becomes infamous as “the buttercup muncher”, with wanted posters/the equivalent of them around.

Flowey Run/AU: Flowey tells Asgore Chara's real cause of death. “Chara was killed by buttercups” is misinterpreted as “plant monsters resembling flowers killed Chara”, which leads to a lot of inconvenience...

Flowey Run/AU: In a case of mistaken identity, Flowey is blamed for killing Chara. Papyrus tries to defend Flowey.

(EDIT on June 18 2019: The author originally mis-numbered this and a few other pages. Oops.)

Most timelines: W.D. Gaster learns parkour (a crucial principle of which is learning how to fall “properly”) just so he doesn't fall into things.

Post-Pacifist: Frisk calls people at unpredictable times warning them about things that would cause them to die or incur diplomatic scandals. People think Frisk has an uncanny sense of intuition.

Flowey Run: Using his knowledge of countless “Flowey Runs”, Flowey sells advice to people and makes quite a profit.

Most timelines: W.D. Gaster, thinking everyone has forgotten about him, repeatedly introduces himself. It turns out it's not everyone else who has memory problems, but him.

Most timelines: Asgore eats a foot-long submarine sandwich, a reasonable size for a monster as big as him.

Most timelines: Sans has to get a bowel treatment. (e.g., a medical treatment for his bowels such as a colonoscopy) It is never explained why.

AU: Chara remembers an obscure detail on the origins of Halloween/Samhain, and exploits this to get through the Barrier with Asriel.

AU: Chara learns a new variety of chocolate (ruby chocolate) has been invented since they died.

AU: Frisk rewrites reality via the SAVE File in order to eat a dummied-out healing item.

Most timelines: Sans finally opens up, disclosing his big, terrible secret...sometimes he eats hot dogs from the wrong end, the left end rather than the right.

Most timelines: Sans/Papyrus find it difficult to eat with chopsticks while wearing mittens. (inspired by Over the Void)
