Rango, an upcoming computer-animated comedy movie, got its crazy popularity long before its release date. Thanks to great advertising efforts, especially on casual game market, only the most incurious persons couldn't note this film. So Zynga, a leading creator of the majority successful game applications on Facebook, has made its own contribution to promoting soon coming comedy movie.

So, well-familiar time management social game FrontierVille has its first promotional Goal titled "Find the Sheriff of Dirt". Now it is up to you to explore that small frontier town in order to find Rango. Let's learn how to do this.

While you are running on your own town bubbling with different creatures, you need to find this pet chameleon nine times. He can appear when you accomplish your usual tasks like breeding animals, clearing homestead and so on. Just click on Rango when you see him.

Then, go to ask your Facebook friends for 10 Buckets of Water to be able to watch he Rango trailer, and then be rewarded for all your efforts. Well, that trailer is not too long and nice to watch but the reward turns out to be too low: 30 coins and three Tools.

All in all, "Find the Sheriff of Dirt" is just an ordinary advertisement trick, so you shouldn't expect any challenge from these sort of tasks. The mission will be available until March 6, 2011
