Mad Chemist (PVZ TLH)

Not to be confused with the Mad Chemist from PvZ Heroes

Overview:
The Mad Chemist is a Gravestone zombie that can be a big threat if you let him live long enough. He attacks with limited amounts of potions (two in fact) but will destroy plants very quickly if you let him live long.

Almanac Entry
Toughness: Average

Speed: Creeper

Description: Forgot there's something called combining

Attacks

 * Blue Potion: The first potion thrown, do medium damage to a 2x2 area of plants.
 * Purple Potion: The second (and last) potion thrown, doing small damage over time to a 2x2 area of plants.

Strategies
Besides putting a Grave Buster on the gravestone, another strategy is to put a cheap plant in front of it as soon as it's revealed so he'll waste all of his potions on their first state and then you can just destroy him.

Potion State Table
As the Mad Chemist keeps living on, his potions keeps getting more and more powerful so here's a chart to keep track of the damage they do. Each potion's max stage is six, were they will start bubbling and shaking and eventually explode, doing it's stage six effect but in a 3x3 area instead and destroying the Mad Chemist.

Trivia:

 * This is the second zombie made by Davidjnzhu0306 that's not in PvZ Heroes
