Also, new challenge:

FF-23, use for dealing with zombies only a single strawburst, for defensive plants only garlics and sweet potato. Also don't use plant food on straw burst.

Easy mode - how I said.

Kinda hard mode - you can use plant food only on garlic, to make droid zombie move on another line.
