The serie "Tremors"

Perfection Valley, Nevada is a quaint little town. The inhabitants live peaceful, tranquil lives. Most of the time. Perfection is home to the Graboid, El Blanco. El Blanco is a 30-foot worm creature who hunts prey by sound. It is an endangered species, so as long as El Blanco is around, Perfection can't be bulldozed by any greedy developers. To protect their home, the people of Perfection must co-exist with El Blanco, dealing with him when necessary as well as other strange situations that come their way.
