This sound is widely associated with Knuckles and is often tagged by users as a Sonic Boom meme clip. Online, it spread through short reaction edits, gaming memes, and reposted soundboard clips because the line is so brief and easy to drop into awkward or uncertain moments. Its staying power comes from how flexible it is: creators can use it for genuine confusion, sarcastic non-answers, or a quick punchline after an overly serious setup. The simple delivery makes it recognizable even in very short edits.
About this sound
A short Knuckles voice clip saying "I don't know," commonly linked to Sonic Boom memes and reaction edits when someone has no answer.
This clip is a brief, deadpan Knuckles line saying, “I don’t know.” It lands quickly, with a flat, slightly clueless delivery that makes the moment funnier the shorter the setup is. Creators use it as a reaction sound when a question goes unanswered, when someone is obviously guessing, or when a scene cuts to pure confusion. Because it is under two seconds, it works well in fast meme edits, gaming compilations, and reply videos where you want a character reaction that feels dismissive, awkward, or unintentionally honest.
