At about 1.25 seconds, this clip is compact enough for reaction edits and usually needs no trimming. Download the MP3 to keep a local copy for offline playback or import it into your editor or soundboard. Its clear voice can sit above music, but lower busy background audio so the ending remains audible. You can also assign the file as a ringtone or notification tone if your device supports custom audio. For a longer celebratory sequence, follow it with a Yaaaay cheer rather than overlapping both sounds.

Play the Undertale Oh Yes button, download the 1.25-second MP3, or set it as a ringtone. Use its drawn-out delivery for smug and playful reactions.
This clip is a quick, theatrical 'Oh, yes' from Undertale, delivered with a drawn-out, confident tone that makes it instantly feel smug and dramatic. It is the kind of reaction sound people add when a joke lands, a reveal gets extra flair, or someone wants to act overly pleased with themselves. Even though it is only a little over a second long, the voice has a polished, showy attitude that gives edits a playful wink and makes ordinary moments feel intentionally overperformed.
