The music is credited to Laura Shigihara, a composer widely associated with the playful, cartoonish sound of Plants vs Zombies, and the title plays on that game's famous zombie demand for brains. That combination of a catchy tune and a recognisable undead joke helped the clip circulate among gamers and meme editors, who reuse it as shorthand for a harmless, funny zombie moment. It survives because it is instantly understood, even by viewers who have never played the game, and it fits short videos, streams and Halloween edits without needing any explanation.
