After the old mayor was ousted, the townspeople of Dirt (led by Rango) construct a coaster out of a k'nex set that a human child lost on the side of the road. They were even helped by Rattlesnake Jake himself.

Credit to Ulvenwood for inspiration on Rattlesnake Jake's head, and to Mekkit for one of the buildings. Also, the round saloon building is made out of an old gas can, just like in the movie. I also tried to make a clock tower (just like in the movie).
