In Gippsland Australia, the coal mines were the biggest source of industry in the small town of Korumburra (pop. 3,600), but now they had shut down and the people did not know what to do. Other than the coal mines, Korumburra is only known for one thing: its great Gippsland gurgling earthworm. These worms can reach 12 feet long and they make a deep gurgling noise. The citizens turned to this natural resource to revive the industry in their town. Toy earthworms were made and sold in the local shops. The people of the town held yearly worm festivals and parades. They even chose an earthworm queen in a beauty pageant. All these activities are great tourist attractions now.

The town in the midst of economic loss and devastation discovered the one thing that made them unique. That one unique thing was the answer to their dire situation.

Note: This is true but 12' would be rare. 6-10' is fairly common when they stretch out. You can search "Gippsland Gurgling Earthworm" and see the pictures. They are also commonly known as karmai, taken from the Bunwurrung language.
