Peashooter

Peashooter is the most primary attacking plant in the Plants vs. Zombies series. It is a peashooting plant, and shoots one pea at a time. It is the first available plant in all of the Plants vs. Zombies games.

Plants vs. Zombies
Peashooter is the only regular offensive plant available until the Snow Pea is unlocked after beating Level 1-6.

Plants vs. Zombies Adventures
Peashooter is the only plant that doesn't need to be unlocked by beating a level or reclaiming a lot. It is available from the start of the game, and the only regular offensive plant available until the Aspearagus is unlocked after reclaiming The Plantagon Lot.

Plants vs. Zombies 2: It's About Time
Peashooter is once again the first plant available and it again costs 100 sun.

Plant Food Upgrade
It can be upgraded to Gatling Pea  temporarily by using Plant Food.

Description
Peashooters have a long tube for their mouth which is where they shoot peas at a normal rate which deal damage to zombies. In the mini-game ZomBotany, they are the first plant/zombie combination found.

Strategies
The Peashooter is the main standard source of firepower in your floral arsenal and the first offensive plant available to the player. Peashooters should be planted in the lane of an oncoming zombie, where it will fire upon the zombie with peas until it has been neutralized. Peashooters are useful for early defense, as once the player has sufficient sun, perhaps from Potato Mines, more powerful offensive plants should be planted instead of the Peashooter.

Peashooting plants of any type are not recommended for use in 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 Peashooters and other related plants should be used is when aiming for the Grounded achievement. They can also be used on the flat portion of the roof, though they may need to be reinforced with Pumpkins, as they become more vulnerable to attacks, especially ambush zombies. Peashooters are great for killing basic zombies but are not to be used for more powerful zombies like Buckethead Zombies.

Heat Wave Mini-game
The only offensive plants available in this mini-game are Peashooters, which must be used to their full potential. Tough zombies that would normally absorb too many peas appear frequently throughout Heat Wave. The Peashooter, at first glance, would seem to operate as if it was under normal circumstances. However, immediately after shouting into the microphone of the DS, some of the Peashooters on screen will gain an orange tint and begin shooting a constant stream of peas at the same rate as a Gatling Pea. When this occurs, use these Peashooters to defeat tougher zombies. However, remember to keep them so, as over time, the Peashooters will eventually tire out and turn a tint of brown.

During the level, some Peashooters may don a brownish tint and slow their shooting. They will exchange their brown tint for an orange one upon shouting into the microphone. Move these Peashooters to a different row from that of the zombies' advance, so as to preserve them for later use.
