Damage per shot

Explanation
Normal Damage Shots are the basic measurement of damage in Plants Versus Zombies and are equal to one Pea of damage. A bite from a Zombie may be referred to as one Normal Damage Shot, but this is disproved in ZomBotany and ZomBotany 2 where the Peashooting ZomBotany Zombies do less damage with Peas than with bites. However, this is proved when you hypnotise a zombie, because the bites from hypnotised zombies do the same amount of damage as a Normal Damage Projectile.

Trivia

 * This may be because hypnotised zombies are weakened in strength.
 * However, it is strange that they are not slowed down.
