Its plant counterpart is the Wood Shield Weed in Plants vs. Zombies: Garden Warfare 2 and Leaf Shield Weed in Plants vs. Zombies: Battle for Neighborville. It attacks plants with its screen door. There is a pirate version that only appears in the Garden Ops maps Port Scallywag and Sharkbite Shores.
Its attacks are Zombie Hurt and Hard Rock Toss. Each Zombie Hurt attack deals 15 damage and each Hard Rock Toss deals 25 damage, which will be used once it loses its screen door.
The screen door has 400 health.
When carrying the screen door, the zombie has about 150 health.
After losing the screen door, the zombie has about 85 health.
Strategies
Screen Door Zombie shields the front of itself, and all damage done to the shield will not hurt the zombie. However, the Chomper's chomp attack will directly damage the zombie no matter what side it is being attacked on. Gooping the zombie will also allow others to get around the shield and attack the zombie directly behind, allowing for easier vanquishes.
The Spikeweed can destroy the shield when the zombie is caught in it. Cactus' Potato Mines deals direct damage to the zombie as well. Goop-shrooms and Fume-shrooms also ignore his screen door. These plants are also very good at defending gardens, so Screen Door Zombies will not have a chance to attack your garden. As a Peashooter, use Hyper to get around back, so you can shoot him from behind, or launch a Chili Bean Bomb or Sombrero Bean Bomb to vanquish this zombie instantly.
