Peashooter

The  is the very first plant obtained in Plants vs. Zombies, and the first combative plant used by the player. It is the only regular offensive plant available until the Snow Pea is unlocked in Level 1-7.

Peashooters have a long tube as their mouth. They shoot little peas out of tube to defeat zombies.

Usage
The Peashooter shoots peas at what is considered a 'normal' rate. It can kill a regular Zombie in 10 shots.

Peashooters are your first line of defense. They shoot peas at attacking zombies.

How can a single plant grow and shoot so many peas so quickly? Peashooter says, "Hard work, commitment, and a healthy, well-balanced breakfast of sunlight and high-fiber carbon dioxide make it all possible."

Strategy
The Peashooter is the standard firepower in your floral arsenal, and the first offensive plant made available to the player. This is the only plant used in Level 1-1 in Adventure mode. The plant is meant to be placed in the lane of an oncoming zombie, where it will fire upon the zombie with peas until it has been neutralized (fires one pea per 1.4 seconds). Peashooters are useful for early defense, so once the player has sufficient Sun, perhaps from Potato Mines, better offensive plants like the Snow Pea and Repeater should be added to the row for a more powerful attack. This is one of the five plants meant to be planted only at the start of a level; the other four are Puff-shroom, Sea-shroom, Cabbage-pult and Lily Pad. The Peashooter should also be planted in a Pumpkin for more defense.

Peashooting plants of any variety are not recommended for the roof levels, as they cannot shoot over the sloping angle of the roof unless they are in the first sloped column. The only time when you should use them is when trying to earn the Grounded Achievement. Apart from placing them in said column, they can also be used on the flat portion of the roof, though they become may be needed to be reinforced with Pumpkins, as they become more vulnerable to attacks. Peashooters are great for killing basic Zombies, but they can barely kill Conehead Zombies and they won't hurt heavily armored zombies such as a Buckethead Zombies as much as the other 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/DSiWare 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, Gargantuar 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).
