Peashooter

The Peashooter is the first plant that you can build. It is the only plant that you can build the first time you play level 1-1.

The design for the Peashooter appears to be loosely based on the Codonopsis pilosula[1], a type of bellflower, and its weapon a reference to Pisum sativum

Its name is a pun on "pea" and "pea shooter", a toy consisting of a long tube that the user can blow through to shoot dried peas or small bits of paper, or alternatively, slang for a weak gun.

Usage
The Peashooter shoots peas at what is considered a "normal" rate (approx. one pea every 1.4 seconds). It can decapitate a basic zombie in ten shots.

Suburban Almanac Entry
Peashooter Peashooters are your first line of defense. They shoot peas to attack zombies. Damage: normal 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
Especially in the earliest levels, before you unlock the Repeater, the Peashooter is going to be the standard firepower in your floral arsenal. By the time the first zombie arrives on any level, you should have enough sun to plant a Peashooter. Put the plant in the lane of the oncoming zombie, it should easily take out the attacker before it does any damage. Peashooters are really only good for early defense. Once you have two or three per row (or enough sun), you should start to plant stronger plants instead, like the Snow Pea and Repeater.

An alternative to planting Peashooters is to plant potato mines for the first part of the levels; if this is done, you should have enough sun to plant strong plants (such as Repeaters) right away.

Peashooters of any variety are not recommended for the roof levels, because they cannot shoot over the sloping angle of the roof, unless they are in the first sloped column.
