You should be able to see the tree of wisdom when you have finished the adventure mode. It will appear in Crazy Dave's shop and will cost $10000. The tree of wisdom will give you helpful tips or things that you may already know.

Many of the codes / cheats in Plants Vs Zombies will only be allowed if you have your tree of wisdom grown to a certain height. There are several sites that contain codes and cheats for Plants Vs Zombies, but the only thing I have ever seen actually "cheat", like unlimited sun, etc, are all trainers. I cannot speak to trainers, they can be unstable at best and can cause the game to crash, but I have put a link below to a site that has codes and unlockable items that you may find useful.
The only ways I know it is to find a picture of it and paste it there or for an avatar (icon) you can go to the plants vs zombies website here:http://www.popcap.com/extras/pvz/ and click Zombatar.
Go to upgrade app store and it will be free to download? Plant vs zombies 3.69.321 version?
i don't know go find the answer from somewhere else
