Extra Level 5

I have played this many times, but can't get three stars. Anyone? I have followed the strategy in the guide and and several others to no avail. Hints?

where did you find a strategy guide???

Nevermind LOL

General tips that worked for me. Collect bushes as soon as they become available. Upgrade the farm before fully upgrading the quarry. No need to waste food trading for gold...there will be enough gold once you send the wizard to take care of the fog. Leave the dragons in the upper right until after the large dragon to the left is taken care of.
