Defeat Final Boss
When you battle the final Boss he will launch massive fire balls and ice balls at your plants. These will crush everything in their path except for zombies. The ice balls can be destroyed by using a Chili Pepper in that row. The fire ball is destroyed by using an Ice Shroom but must have a Coffee Bean or else it will fall asleep.
