If you do not like the cards from Crazy Dave, exit the game and restart. The cards will change randomly.
Defeating the Final Boss
The final Boss will launch massive fire balls and ice balls at your plants. They will crush everything in their path except for zombies (basically, all plants in that row). To destroy the ice ball, use a Chili Pepper in that row. To destroy the fire ball, use an Ice Shroom, but also with a Coffee Bean or else it will fall asleep.
Ultimate Lawn Defence Using Infinite Sun Cheat
"Dr. Zomboss": Easy completion
When Dr. Zomboss comes down to throw an ice ball or fire ball, you can use Freeze Shrooms to freeze him. This allows your various pults time to get some damage on Dr. Zomboss himself. Jalapenos will also cause damage to him when he is down to toss a fire or ice ball. The more damage you can do to Dr. Zomboss, the faster and easier it is to end this level. Save at least one Freeze Shroom and one Jalapeno for whatever he tosses.
Zombie Mini-games: Earning Sun
The only way to earn sun in the zombie mini-games is to kill sunflowers. First, put a good zombie for the situation in the lane you want it to go in. Make sure that there are sunflowers planted in that lane. Collect the sun when the zombie eats the flower, then buy more items and eat the brains.
Fertilizer First Time
The first time Crazy Dave allows you to start growing your plants, you'll start off with two plants; upon feeding them enough water, Crazy Dave will say they need more fertilizer. Instead of buying the fertilizer, simply hit back. You won't get charged for the price of the fertilizer!
