The sound comes from Pou, the popular virtual pet mobile game released in the early 2010s. Players hear it when feeding Pou, which made it one of the small audio cues many people remember from the app. Online, the clip spread through short meme edits, nostalgic game posts and soundboard uploads because it is brief, clear and instantly tied to a specific phone game era. It is still used when creators want a simple cartoon eating effect with recognizable mobile game nostalgia.
