Snap Pea

Snap Pea is a premium plant in Plants vs. Zombies 2 that was introduced in the 7.1.3 update. It instantly kills a zombie in front of it when planted, then shoots the zombie's head that deals 400 damage per shot to any zombie. It will then rest for ten seconds before killing another zombie. If it can't eat a zombie, such as machines or Gargantuars, it will shoot three peas at the zombie.

Like Shadow Peashooter, Goo Peashooter and Sling Pea, Snap Pea will require 250 seed packets to be unlocked. The player can do so by replaying Jurassic Marsh levels to earn Piñatas from the piñata tracker.

Origins
Its appearance resembles a mix between a Peashooter and a Chomper, with the Chomper head being based on a pea pod. Its name is based on the snap pea, a cultivar group of edible potted peas and is a reference to how it "snaps" (eats) up zombies with its huge mouth after burrowing.

Plant Food effect
When fed Plant Food, Snap Pea will burrow underground and snap up five random zombies, and then return to shoot all five heads in its lane, with each head dealing incredibly high damage. If its only targets are machines or Gargantuars, it will shoot three peas at them instead.

Strategies
Using this plant can be a good counter against zombies that have some sort of countermeasure against certain plants, such as the Excavator Zombie immune to straight shots, Parasol Zombie which is immune to lobbed shots, and Imp Dragon which is immune to fire attacks. This plant will eliminate those threats in a matter of seconds; thereby allowing your other plants to have an easier time killing more aggressive zombies when they're at lower levels.

Trivia

 * It can eat a zombie that is trapped in a frozen block.
