Growing the Tree of Wisdom for 100 feet requires 94 bags of Tree Food and $245,000. To make this easier, Play the Survival: Endless and Last Stand; use money from Zen Garden; kill Zombie Yeti; and play the mini games Wall-nut Bowling 2 and I, Zombie.
When you are in fog and need light (and you do not have a lantern), use the torch wood if you have the sun. It shows you the space in front of it.
Get all the trophies in Mini-Games, Puzzle, and Survival modes.
The achievements are displayed as an underground list. Scroll through the list and keep going down to see various hidden objects including a zombie, the bookworm from Bookworm, jewels from Bejeweled, a unicorn fossil, and finally Chinese zombies staring back down the hole.
Disable full screen mode. Go to your zen garden. After feeding the plants, it will normally take thirty minutes to feed them again. To feed them all, change the system time to an earlier value. This will increase their growth.
To kill Bungees, use Chompers, Squash, Ice Shroom, Jalapeno, or an Umbrella Plant.
If you do not like the cards from Crazy Dave, exit the game and restart. The cards will change randomly.
