Complete a level without any plants getting KO'd!
Vegemight is an achievement in Plants vs. Zombies Adventures that is earned by completing a level without having any plants KO'd. Even if they are revived, the player still will not get the achievement.
You can just start the first level keeping the Peashooters away from the zombies and not letting them get killed as an easy strategy. In the early levels, it was quite easy to earn. However, as progress continues, the zombie toughness and numbers get bigger, making it more difficult.
- The achievement's name is a portmanteau of "Vegemite", an Australian paste made from yeast extract and "might", meaning great and impressive power or strength.
