Pod Squad

Difficulty: Medium-hard (easy on Conveyor-Belt levels and Last Stand)

Pod Squad is an achievement in Plants vs. Zombies 2: It's About Time. It requires the player to max out a Pea Pod while it's on a mine cart. It is worth 15 points on Game Center for iOS devices and 1,500 XP on Android devices.

Strategies
Mine carts are actually one of the best places to put maxed out Pea Pods as it lets the plant cover more than one lane as needed. Thus the achievement leads players towards a viable defense strategy. 625 sun needs to be spent to max out the Pea Pod. A good level to do this is in a last stand level, so you can put down 5 Pea Pods and be done.

You can easily do this in the Wild West - Days 8, 6, 18, or 25. But it is best done at Day 8.

Trivia

 * This and Shell on Wheels are the only achievements which require to use a Cart and Track.
