Screen door

The Screen Door is a shield used by the Screen Door Zombie; it distinguishes it from the normal zombie. It's the strongest shield in the game. The player must use strong defense and offense plants against this zombie.

Overview
It takes 55 normal damage shots (e.g. Peas, Spores) to destroy the Screen Door. It has a high toughness equivalent to the Bucket, only the door protects the zombie from Snow Pea and Fire Pea attacks. Fumes and Lobbed-shots projectiles can hit the Zombies without having to destroy the screen door. Much like the way Fumes and Lobbed-shots don't have destroy the screen door, Spikeweed doesn't need to destroy the screen door since the zombie steps on it. Appearance changes upon absorption of 19 and 37 normal damage shots.

Trivia

 * When the Cattail shoots a spike the zombie's back, the damage is dealt to the screen door for unknown reasons.
 * When a Screen Door Zombie is eating a plant, he puts his Screen Door on the ground, but damage is still dealt to the Screen Door.
 * Sometimes, a screen door appears in black (in fact a burnt one).
