| Ain't Ground, Look Down!|
Defeat at least 5 Digger Zombies and 1 Giga Digger Zombie in some levels without using any Split Plants, Magnet-shrooms or any plants that can hit Digger Zombies underground
Actually, the achievement only said that you can't use Split Plants, so you can still use Cob Cannon, Cattail, Gloom-shroom and their other types. You cannot use Starfruit or Star-Juice to kill it.
- This name is references to the song "Ain't got Rhythm!" in Phineas and Ferb
