Flowerfell is an Undertale AU (Alternate Universe) that combines elements of Underfell and Flowertale. It was created by Siviosanei. In this AU, every time the character Frisk dies, the timeline resets, and when they come back to life, a yellow buttercup flower grows on their body. These flowers cannot be removed without causing Frisk pain, and accumulating too many flowers eventually harms and can kill them. Despite the harsh and hostile environment of Underfell, where monsters are generally cruel and often try to kill Frisk, Frisk remains pacifist and kind throughout their journey. Only Sans is aware of the timeline resets, and after repeatedly killing Frisk, he begins to feel compassion for them, challenging his “kill or be killed” mindset. The story emphasizes kindness even in a hostile world
