Thrilling the Zombies (Walk This Way in the Steam version) was an achievement unlockable on the old iOS and Steam versions of Plants vs. Zombies. It required the player to hypnotize a Dancing Zombie. This is the equivalent of the Disco is Undead achievement in newer versions of the game. It was replaced by Disco is Undead after the Dancing Zombie got redesigned.
- See Disco is Undead.
- This achievement was one of the first of the first twelve achievements to be in the old Steam version of Plants vs. Zombies since May 8, 2009.
- The name was a tribute to Michael Jackson's album Thriller, since the old Dancing Zombie was based on Thriller.
- The achievement's previous name (current name in the Steam version) was a possible reference to the song Walk This Way, a song by the American rock band Aerosmith.
