Angry Birds began as a mobile puzzle game from Finnish developer Rovio, first released in 2009, where players launch birds at structures to defeat green pigs. Completing a level triggers this short victory jingle, which became instantly recognisable as the game spread to hundreds of millions of phones and spawned sequels, merchandise and films. Today creators still reach for it because it carries instant, wordless meaning: a level cleared, a task done, a small win earned, all wrapped in early smartphone nostalgia.
