Modern Day - Day 9

Modern Day - Day 9 is the ninth level of Modern Day. This level marks the first appearance of Balloon Zombie.

Strategy
There are two aspects that make this level very hard. On the one hand, since the players is in lack of high offensive plants, Balloon Zombies will easily fly over the player's defence with their high speed and health; on the other hand, the combo of Explorer Zombies, Punk Zombies and Tomb Raiser Zombies is deadly since the tombstones provide considerable protection for the Explorer Zombies and Punk Zombies to destroy the player's plants. The core idea to win this level is to plant as many Nightshades as possible to generate enough offensive power. In other words, the player does not need to plant many Moonflowers, since all of the plants in this level are cheap. More space should be saved for the Nightshades, with separated Moonflowers to power them up. The plant food given is suggested to be used on the Nightshades on the back most column, and Gravebuster need to be continuously used to remove high-threatening tombstones. And finally, use Thyme Warp as life saver when the situation gets really tough, but do not use it too early, given its very slow recharge speed.
