Plants vs. Zombies is PopCap's 2009 tower defense game where waves of zombies shuffle across a lawn trying to eat the player's plants and reach the house. The eating noises became part of the game's cartoon charm, with zombies audibly chomping as they advance. Clips of that munching were later ripped and shared on soundboards and in edits, detached from gameplay. It stays popular because the sound alone signals a zombie happily eating, making it reusable for any greedy, satisfied eating joke.
