This clip belongs to the Woodles Sound Collection, a user-generated library of short cartoon-style effects tagged alongside Mickey Mouse content, and it appears to be the second ear-wiggle take in a small series, following on from an earlier ears entry. Short sfx like this circulate widely on soundboards because editors need tiny, reusable stings they can drop into reaction videos, gaming clips and animated memes, and this one has found a quiet niche as a cute character-motion accent rather than a mainstream viral hit.
