Opera Zombie

Opera Zombie is a zombie that sings occasionally, so that some plants focus on her

Strategy
It will still work without music, But since it's weak and the sing dosen't do any damage at all, 1 instant kill (excluding squash) can kill a single Opera Zombie

Trivia

 * It has a Jack-In-The-Box Zombie's jaw.
 * The sound she will make is only a scream, due to the fact, at the Almanac Entry, Her opera are actually girl screams.
