M is for Metal

M is for Metal is the fifth level of Vasebreaker. It includes several zombies with magnetic equipment and some Magnet-shrooms to take away such equipment.

Strategies
Plant Magnet-shrooms in front of the lawn and protect them with Pumpkins if necessary. Plant left-facing Repeaters on lanes with exposed Buckethead Zombies or Football Zombies, and plant Squash near any zombies who come too close or are in a lane clear of vases. Place Hypno-shrooms on the left side, in case a zombie gets away. There is no time limit, and you can let out the zombies whenever you choose to, so a viable, but slow strategy is to wait until Magnet-shrooms recharge before breaking certain vases.

Trivia

 * The level name is a reference to the mnemonic "(letter) is for (word that starts with the same letter)." It says metal because most of the zombies can have their armor stolen from them by a Magnet-shroom.
 * This is the only Vasebreaker level with the Magnet-shroom and Pumpkin.
 * In this level, it may be possible for the Jack-in-the-Box Zombie to get into the house without its Jack-in-the-Box if there is a Magnet-shroom next to it, as it will steal its Jack-in-the-Box, allowing it to walk freely.
 * This is also the only Vasebreaker level where the player can avoid having its Jack-in-the-Box explode, although it is possible to kill it with a perfectly timed Squash or other instant-kill plants.
