Dead Zeppelin

Dead Zeppelin is the fifth level of I, Zombie in Plants vs. Zombies and Plants vs. Zombies: Journey to the West. It focuses on Balloon Zombies.

Strategies
Use Bungee Zombies to get rid of Magnet-shrooms and Cacti when you have enough sun. Then, use Buckethead Zombies in rows with heavy offense and Balloon Zombies with even heavier offense. However, do not use them in lanes with Cactus, otherwise, they will be wasted. Use a Bungee Zombie to remove them before you send in a Balloon Zombie.

Trivia

 * Dead Zeppelin is the only I, Zombie level that includes the Balloon Zombie and the Cactus.
 * Dead Zeppelin is a reference to the 1970's rock band Led Zeppelin.
 * If a Balloon Zombie enters a lane where the brains are already eaten, it will continue floating past without its balloon popping.
