Ask Me About Mustache Mode

Difficulty: Very Easy

Ask Me About Mustache Mode is an achievement the player can earn if the player purchased Plants vs. Zombies through Steam.

To earn this achievement, simply type "mustache" (or "moustache"), which is a code, while playing the game or in the Main Menu, making the zombies' appearances have mustaches. You can earn this achievement the first time you play.

Trivia

 * The non-Steam version of the game simply calls this as 'Mustache Mode'.
 * This is the easiest achievement to obtain in all versions, just as easy as the Down the Hole! achievement.
 * This is the only achievement related to activating a code.
 * It will only effect a Zombie and his variations, like Buckethead Zombie and Pole Vaulting Zombie.
 * Zombies with mustaches have normal strength due to it being accessories.
 * When you kill a Zombie with mustache, the mustache will fall along with the zombie's head.
 * The new Backup Dancers already have a mustache, so if you activate this, it won't affect the Backup Dancer.
 * You can earn it even without the Tree of Wisdom.
 * On the the DS front cover there is a Conehead Zombie with a mustache.
