Beat Ancient Egypt - Day 3 using only Puff-shroom, Grave Buster, Iceberg Lettuce, and Imitater (you may choose only from the three plants above to imitate). No Power-Ups, Boosts, or Plant Food is allowed (except for the ones the zombies drop). You may not lose a single lawn mower.

You must choose other plants to begin the level, since I have only chosen four. However, you must not use them, only the free plants chosen for you.

Here's the catch: You may not use a single Plant Food on your Puff-shrooms. This way, you are forced to constantly replace your offensive line.
