Plants vs Zombies launched in 2009 from PopCap Games as a tower defense game where garden plants defend a house from waves of zombies. Its soundtrack by Laura Shigihara gave each stage a playful, memorable identity, and the short victory cue became the audio shorthand for clearing a level. As gameplay clips, edits and memes spread online, players began lifting that fanfare out of the game and dropping it onto real life wins, challenge finishes and comeback moments, where its cheerful tone still reads instantly as success.
