Encounters
Ancient Egypt: Days 28, 29, 30, 32, and 35

Far Future: Days 28, 29, 31, 32, 33, 34, 35

Strategies
Brickhead Zombie and his variants can take quite a beating, so resort to instant-kill plants to take them out. Grimrose, which is found in Modern Day, is effective at taking them out, but against groups of them, use area of effect plants like Cherry Bomb, Grapeshot, or Primal Potato Mine. You could also use Primal Peashooters to stall them as they take in damage. Using Shadow-shroom, Hypno-shroom, Chomper, Toadstool, and Chili Bean can help because they ignore their headwear. If you have enough sun for it, you can use a Magnifying Grass to take care of their headwear in a couple of hits.
