Bones N Pellets is the friendship between Flowey and Sans from the Undertale fandom.

Canon

Neutral Route

When the player is asked to go on a break with Sans once they reach Waterfall, he will take them to Grillby's and act unusually serious when asking them if they had every heard anything of "talking flowers". Regardless if the player answers "yes" or "no", Sans will make the player believe he just means the "echo flowers" that repeat things that have been said in front of them. Things get "interesting" when Sans tells them that his brother Papyrus had been talking to a flower that had unique responses. He admits that he finds that weird. Sans was (supposedly) not there when the player fought Flowey's monstrous form at the end of the route, though he does call the player once Flowey is defeated to inform them of what had happened since the human had left the Underground.

Genocide Route

When allying himself with the player and gets to the fight with Papyrus, Flowey openly mocks his "garbage brother" and is glad that Papyrus did not invite him along. But then Flowey's tone gets a bit more serious as he warns the player to not let Papyrus' brother find out anything about them. He does not elaborate beyond Sans causing him "more than [Flowey's] fair share of resets", implying that Flowey made the mistake of killing Papyrus in another timeline and learned that Sans is not to be messed with.

True Pacifist Route

When the player manages to trigger all the events that lead to the best possible ending, Sans and every other monster the human had befriended will come to the player's aid in (what is supposed to be) the final battle. However, when they start to question how all of them knew to come here at the same time, Flowey reveals himself; it was all a trap set by him. He then ensared all the monsters present and attempts to kill the human, though the monsters band together to protect it from his attacks, with Sans even mocking Flowey to encourage the player to defeat him. However, Flowey then manages to absorb his soul alongside the ones from every monster present and reveals his true form to fight the player. Trapped inside as a Lost Soul, Sans is telling the player to give up, like he did, but the human manages to snap him out of it. Once the final battle is over, everyone will wake up near a bed of flowers underground, though the details of the event are fuzzy in their memories.

Fanon

Though there are quite a few Flowey/Sans fics out there, fans prefer the idea of a platonic team-up between them, given that they are shown to be the most powerful characters in the setting. A common theme in fanwork is Flowey somehow possessing Sans of fusing with him against his will to harness his power for genocidal purposes. Sans' status as the fandom bicycle also contributes to the ship.

There are over a hundred fics featuring this friendship on AO3. The romantic ship currently has only 60, indicating that it is popular, but most people aren't keen on the idea of shipping them romantically.
