Flowey apppears saying "AHAHA TOO BAD" and stab Asgore with a knife, causing him to melt while screaming, while Frisk reacts with a overdramatic gasp. After flowey gives Frisk the "I told you so" about his kill or be killed plosphy. After a shrill laugh he hits a button labled "close the fucking game" and it ends up closing the fucking game. This causes Sr Pelo on the other side to slam the table in rage. After rebooting the game, Photoshop Flowey appears while Frisk is screaming. Flowey then tells Frisk about his plan to kill them over and over until Frisk interrupts saying that they will fight Flowey. Flowey laughs calling them an idiot and then proceeds to crush them, causing a gameover. Flowey then procceds to crash the game again causing Sr Pelo to rage even more. After rebooting the game Frisk calls for help saying "HALP MEH", the Souls then start to help, but not before arguing about their gender (Frisk). They end up giving Frisk a hulk like shape that allows them to power-slap Photoshop Flowey. Flowey, about to die ends up resetting his SAVE state causing Frisk and Sr Pelo to be overflowed with memes. Flowey then states he is god because he has Netflix on the go (lucky) this causes Frisk to ask for help, the Souls then overpower Flowey leaving him in his flower state once again. Frisk then tells Flowey that they are not going to kill him. This causes him to cry and run away. Sr Pelo finishes the game in happiness, that is until Flowey appeares and tells him you need to make friends for the true ending. This causes him to rage and break his table.
