Photoshop Flowey is the transformed final form of Flowey in Undertale, the 2015 role-playing game created by Toby Fox. The encounter sound plays when this distorted version of the flower appears to stop the player, marking one of the game's most unsettling boss fights. Clips of the moment spread through gameplay videos, fan edits and soundboards, where the glitchy audio became shorthand for a corrupted or overpowered villain. It remains popular because Undertale's fan community still remixes its boss battles, and the sound instantly signals a dramatic, sinister reveal.
