Muffet first appeared in Undertale, the 2015 indie role playing game by Toby Fox, as the spider monster who runs a bake sale in Hotland and traps the player in her web during a boss fight. Her polite, tea loving manner contrasts with her threatening laugh, which became a recognizable shorthand for the character among fans. Clips of the laugh later circulated in gameplay videos, fan animations and meme edits, where it is reused far beyond the fight itself for teasing, villainous or deceptively sweet characters.
