A Small Glitch
Well, you know you see cars going by? For this glitch, you need a car and a Toy Shop. If you click on the car and the person walks to the Toy Store, he/she should also buy a balloon. When they get back in their car, at the last nano-second, tap the balloon and the person SHOULD be waving while he's/she's in the car!
Being that Flooz are so hard to come by, I recommend spending them carefully.
You can earn valuable things from your friends, so try and visit their villages on a daily basis.
Pay close attention to your villagers. If they're sulking, look at the icon above their head and figure out how to make them happy.
If you're low on wood, you can plant trees in the forest area.
You can earn extra gold by popping balloons around town. You get a bonus - totalling 100 gold - if you wait for them to drift up into the air first.
