The track comes from Plants vs. Zombies 2, the tower-defence sequel where the pianist zombie performs as a musical undead character rather than a conventional attacker. Its piano-led style fits the game's mix of cartoon horror and comedy, giving a normally scary monster a showy, almost charming personality. Clips of the music later circulated as memes, where creators borrowed it to score entrances, reveals and ironic victories. It remains popular because the contrast between elegant piano and zombie chaos is instantly recognisable and easy to reuse in short edits.
