Strategy
The plants you get in this level are the Ice-shroom, Jalapeno, Cabbage-pult, Kernel-pult, Melon-pult, and Flower Pot.

Dr. Zomboss has 4 attacks. When not doing any of them he will be sending zombies at you.
 * The most common attack is to duck down so you can see his head. After a short delay his eyes will glow either red or blue, signalling his attack:
 * If red, he will unleash a fireball. Use an Ice-shroom to extinguish it.
 * If blue, he will unleash a snowball. Use a Jalapeno to melt it (making sure to plant it in the same row).
 * Another attack is to drop 3 bungee-zombies down, with them hanging on his hand. They will of course steal 3 plants unless you kill them first.
 * If the player plants any plants off of the sloped section of the roof, on the flat part, Dr. Zomboss may squash them with his foot.
 * Dr. Zomboss will throw a camper down on your plants every so often, crushing all of the plants in a 3 wide x 2 tall area instantly.


 * Always have an Ice-shroom and Jalapeno ready for Zomboss' Iceball and Fireball attacks.
 * If possible, save up these two plants for Zomboss' attacks, or for tougher enemies such as Zombonis.
 * Never keep all your Melon-pults next to each other. This helps save plants from the camper thrown by the boss.
 * When Dr. Zomboss ducks down to attack you with an iceball or fireball, use ice-shrooms to freeze him so that your plants have more time to do damage.
 * Avoid using a Jalapeno whilst he is frozen, as this will un-freeze him and let him move away.
 * It is also possible to keep re-freezing him with multiple Ice-Shrooms before and after the attack, providing a huge opening for your plants.
