This sound is widely recognized online as a Flowey quote from Undertale, the 2015 indie RPG by Toby Fox. Short Flowey voice lines spread through memes, animations, and game edits because his sugary delivery often hides obvious malice. That contrast keeps the clip useful years later: it instantly signals insincere approval, manipulation, or a plan that sounds good only on the surface. It still appears in short-form gaming posts, reaction memes, and remix edits built around Undertale characters and dialogue.
About this sound
A short Flowey voice clip from Undertale saying "That's a wonderful idea." People use it for fake support, sinister jokes, and sarcastic reaction edits.
This clip features Flowey from Undertale delivering the line "That's a wonderful idea" in his bright but unsettling voice. The tone sounds cheerful on the surface, yet it carries a manipulative, slightly creepy edge that makes the moment feel sarcastic or suspicious. That contrast is why the sound works so well in edits: it can read as genuine encouragement for a split second, then flip into obvious menace. Creators often use it to underline bad plans, ironic approval, or a character acting way too enthusiastic about something that will clearly go wrong.
