ZomBotany 5

ZomBotany 5 is a variation of ZomBotany that takes place on the roof with new plant/zombie hybrids. (Supposed to be ZomBotany 3 but name has already been taken up).

Plants: Player's choice

Zombies: Cabbage-pult Zombie, Wall-nut Zombie, Kernel-pult Zombie, Tall-nut Zombie, Melon-pult Zombie, Jalapeno Zombie, Squash Zombie, Umbrella Leaf Zombie, Pumpkin Zombie variants (Cabbage-pult Zombie, Kernel-pult Zombie, Melon-pult Zombie, Umbrella Leaf Zombie)

Strategies
The Umbrella Leaf Zombie is the most dangerous, as it can deflect all lobbed shots to protect itself and all zombies in a 3x3 area. As Spikeweeds and Spikerocks cannot be used on the roof, use instant-kills to deal with it as well as other zombies around it. Fortunately, it cannot deflect a Squash.

Next, beware of the Melon-pult Zombie, as it deals heavy damage and also 0.5 bites damage to surrounding plants. A Pumpkin version of this zombie will appear during the final wave, so instant-kill it as well.
