Peashooter Zombie

The Peashooter Zombie moves forward slowly like any other zombie. The difference is, they constantly fire peas in front of them, hitting plants. Each pea has equivalent damage as a bite from other regular zombies. Peashooter Zombies only appear in the ZomBotany mini-games. Wall-Nuts, Tall-Nuts, or Pumpkins are a must to stop peas from destroying your defense. Alternatively, use cheap plants such as sunflowers to temporarily block peas.

Strategy
As they have low toughness, just kill them however you would a regular zombie. However, use defensive plants to protect against their peas.
