The sound comes from Plants vs Zombies, the tower defence game developed by PopCap Games and released in 2009, where players defend their lawn against waves of zombies. It plays when the player defeats Dr. Zomboss, the game's final boss, and completes the main adventure. Since then, players have clipped and shared the win jingle as a shorthand for beating a tough level, and it remains popular in gameplay videos and memes because its upbeat ending is instantly recognisable to anyone who played the original game.
