Unlocked: At start
Planted on: Ground, Lily Pad, Flower Pot
The Peashooter is your basic, go-to attack unit. You get this plant in Level 1-1. The peashooter shoots in a straight line, all the way to the end of the lawn. 10 shots from a peashooter will take down a regular zombie. A peashooter shoots one pea per 1.4 seconds. Peashooters are good for the early game since they don’t cost a lot of sun. Once you have about 2-3 peashooters per lane, it’s best to replace them with stronger attack plants, like a snow pea or a repeater.
Peashooters don’t work on the roof levels since they can’t shoot up the slanted roofline to hit zombies.
Heat Wave Mini-game
Within the Heat Wave mini-game, the Peashooter, at first glance, would seem to operate as it would under normal circumstances. However, immediately after shouting into the microphone on the DS system, some of the Peashooters on screen will gain an orange tint and begin shooting a constant stream of peas. When this occurs, use these Peashooters to defeat tougher zombies, such as the Football Zombie or Buckethead Zombie.
During the level, some Peashooters may take on a brownish tint and slow their shooting. This state will end when you shout into the microphone (though only when able), and they will all become orange-tinted. Move these Peashooters to a different row from that of the zombie’s advance, so as to preserve them for later on (when they are capable of shooting again).
