Matilda is one of the main bird characters in the Angry Birds game series created by Rovio. Her sound became familiar to players through the original mobile game and later entries, where each bird had its own distinct audio cue. Online, creators reuse the Matilda sound in gameplay clips, nostalgic mobile gaming compilations, and short memes that reference early smartphone games. It still gets used because the noise is brief, recognizable, and closely tied to one of the most widely known casual games of the 2010s.
