| Light Artillery|
Won using only Sunflowers and Peashooters!
The easiest level to earn this is the first level where both Sunflowers and Peashooters can be used. Technically speaking, only the Peashooter needs to be used, but it is recommended for Sunflowers to be planted.
- The achievement's name is a play on the words of the phrase "heavy artillery."
- The "light" part of the name may refer to the Peashooter being the weakest plant in the game, however, it may also refer to Sunflower's sun production.
- Despite the description of the achievement, Light Artillery can be earned without planting any Sunflowers.
- Light Artillery, Sniper Squad, and Feel the Beet are all about only placing Sunflowers and another plant.
