Don't Pea in the Pool

Difficulty: Easy-Medium

Don't Pea in the Pool is an Achievement unlockable for the iPhone, iPad, PlayStation Vita, Android and PC versions of Plants vs. Zombies. In order to complete it, the player must complete a Pool level without using Peashooting plants.

Strategy
This is a very simple achievement to unlock, but there is little point in trying it until you beat Adventure Mode. However, once you do all that is necessary is to replace Peashooters with Cabbage-pults, Kernel-pults, Cactus and/or Melon-pults. Cattails are also good to use since they can attack every lane, but this is not recommended for Pool's Closed. Chompers can work too, since they are a replacement and can be used for this Achievement before finishing Adventure Mode. If you have a Coffee Bean you can use Scaredy-shrooms, Puff-shrooms, Sea-shrooms (if you want to plant in the water), or Fume-shrooms. It is possible to get this and the achievement Pool's Closed, by using area of effect plants such as Starfruit and Gloom-shrooms alongside the pool. Overall, you should try for this achievement on Level 3-1, after you completed Adventure Mode at least once. You can still earn the achievement without finishing Adventure mode on level 3-1, by using Chompers, Lily Pads and Wall-nuts, since they protect the Chomper, and there is no zombie that is a threat on the level. Completing Survival: Pool or Survival: Pool (Hard) will also work as well. If you are going to replace peashooting plants with lobbed-shot plants, don't attempt to complete Don't Pea in the Pool on a level that includes Dolphin Rider Zombies, since they can dodge lobbed shots due to their speed. (However, you can use Tall-nuts.) Also, you can find many peashooter-less strategies on the Last Stand strategy page.

Note: Completing a Fog level without using any peashooting plants will not unlock this Achievement because it is not day.
