How do you remove trees fully ?

When you mouse over on a bush, tree, rock, lump of clay, bamboo, etc, wait until the item is outlined in yellow and stay on it. A little bubble with a count will come up, and the larger number on the right will tell you how many times you will need to hit the item to completely get rid of it. You will need to click on the item until the counter on the left reads the same as the number on the right. When your guy is done working, a treasure casket will appear and that will tell you that you have permanently removed the item.

If you have less energy than the tree/stone/item you want to remove, youll either need to buy more energy or get the stone quarry (who removes stones, clay, marble and quartz) or the lumberjack (who removes bamboo, palm and wood) to destroy the item fully
