Are you sure my esteemed 1Zulu? 'cos I'm totally sure that you need 10 peas to kill a regular zombie, so if 1 pea do 20 dmg, then 20 x 10 = 200 dmg < 270 hitpoints...

Yes, I am sure. It's a common misconception that 10 peas kill a regular zombie. If we assume 1 HP = 1 pea, regular zombies have 13.5 HP.

However, they have a "critical point" at 9 HP. What is this critical point business? Well, it's a point after which the next shot will cause the zombie's HP drops rapidly to zero (at a rate of 3 HP/sec), but it is still alive to the game. This means a zombie who's taken 10 shots is still alive for a couple of seconds. Even though it can no longer damage your plants, it will still absorb shots.

This is why zombies who appear dead (lost their head) are still attacked by plants. Plants don't attack dead zombies. Internally, a zombie without its head is not dead yet.
