Shields

Shields are held by zombies. They raise the health of the zombie that holds them; and prevent them from slowing from Snow Peas and Winter Melons.

Types of Shields

 * Newspaper -Absorbs 8 damage slots. Can be bypassed by Catapult Plants.
 * Screen Door -Absorbs 55 damage slots. Can be bypassed by Fume-shrooms and Catapult Plants. Can be taken by a Magnet Shroom.
 * Ladder -Absorbs 32 damage slots. Can be bypassed by Fume-shrooms and Catapult Plants. Can be setup on a defensive plant so that zombies can climb over it. Can be taken by a Magnet Shroom.

Strategy
Newspaper Zombies are the easiest of the bunch to kill. Try to have at least two peas of damage on him, and you should do fine. Screen door zombies are a little harder, but if you have Fume Shrooms, Gloom-shrooms, Magnet Shrooms,or Catapult plants you should do fine. The same goes for the Ladder Zombie. Luckily, you find him on the roof, so you will no doubt have Catapults.

Trivia

 * The Newspaper and the Ladder zombie are the only ones who eat without their hands.
