Bash Potato is an achievement in Plants vs. Zombies 2. It is achieved by killing seven zombies with a single Primal Potato Mine. It is worth 10 points on Game Center and 1,000 XP on Google Play Games for Android devices.
Its name is a portmanteau of "bash," mean to hurt or physically assault someone, meaning the zombies and "mashed potatoes," a dish created by mashing boiled potatoes.
Getting this achievement should be really simple. The player can either do this in an Endless Zone or in a normal level. In a normal level, try to plant a Primal Potato Mine and defensive plants in front of it such as Primal Wall-nut or Tall-nut to bunch the zombies up so you can take out several zombies in one hit. If the player wants to use different defensive plants, the player can use Sweet Potato to lure the zombies towards the lane where Primal Potato Mine is in or even use Garlic as a substitute if they do not have Sweet Potato. You can also plant a Primal Potato Mine between a huge clump of zombies and then quickly using Plant Food on it to arm it.
In Neon Mixtape Tour this can be made even easier. Using Thyme Warp with Primal Potato Mine is very effective, as Thyme Warp will clump the zombies together, making it easy to kill many zombies with a single Primal Potato Mine.
