Pierce-Shooter

Info

 * This plant is very useful when groups of cats appear in a level
 * It costs only 80 sun it shouldn't be bad for planting at least one of each

Strategies

 * Always use at least two of them since it cannot guarantee that it will shoot at any lane. Cats come in various lanes so it is guaranteed that will attack through an entire row
 * Don't use this if you have a very difficult cat-costume to deal with since it can't guarantee that will destroy the whole cat.
 * Always use it with at least 2 sunflowers and one Wall-Nut or 2 Peashooters to produce vivid effects

Trivia

 * This is the first plant that can attack through whole body.
