Strategies

 * This level can be extremely hard if you do not have boosted or upgraded plants, so boosting and/or upgrading plants like Hypno-shroom and Iceberg Lettuce is recommended.
 * Hypno-shroom is the only plant that can damage the Zombot itself. If you hypnotize a Buckethead Cowboy or Cart-Head Zombie it is probably not going to make it back. Since there are a lot of Plant Food in this level, use it on a Hypno-shroom to bring back a hypnotized Gargantuar.
 * Keep in mind that the Electric Currant's fences may or may not kill a Chicken Wrangler Zombie. Do not take chances, however, because the Zombie Chickens run really fast and may eat your brains. Hypno-shroom, Spikeweed or Wall-nut are recommended on each row.
 * Be careful of the Zombot's missile attack, as it can destroy your defenses against the Zombie Chickens.
 * The hardest phase is the third phrase, as Wild West Gargantuars are summoned. These zombies are not only immune to Hypno-shroom (even boosted), but they also can kill a hypnotized Gargantuar if there are any helping zombies like Cart-Head Zombies besides it. For this phrase, hypnotize a lot of zombies and kill the Zombot quickly is your best shot.
 * Using Spikeweed's Plant Food can help trap the Zombot and prevent it moving. This works well if you have any hypnotized Gargantuars on the same lane as it as they can continously smash the helpless Zombot.
