Tremors

Shriekers are spotted in Juniper, Arizona, and Twitchell sends Burt and Tyler to take care of it. However, the Fish and Wildlife Service are also in town and after a failed attempt to kill and contain the Shriekers they have multiplied and are out of control.

With the entire town struggling financially Rosalita decides to take a job at Melvin's latest business venture, the Oasis. But some of the water used in the Oasis' lagoon is contaminated with Mixmaster, which creates a deadly six foot shrimp.

Frank returns to Perfection with some extra help in another attempt to kill El Blanco and retrieve the key he swallowed. Meanwhile, Larry encounters a creature in a barn and tries to figure out what it is.

A plague of strange bugs infest the valley. They start eating dry wood, but they soon move onto meat and start heading toward the town.

Protesters come to Perfection to force Burt and the others out of the valley, claiming their presence is having adverse effects on El Blanco's health. This couldn't have happened at a worse time as El Blanco begins acting very strangely.

The Perfection residents meet a strange old man claiming to be a scientist called Cletus. At first his ramblings of a dangerous monster on the loose are shrugged off as nothing but El Blanco sightings until the residents finally see it for themselves.

Twitchell sends Burt and Tyler to a small town track down a suspected Graboid after a bunch of strange disappearances. But the townspeople believe the real cause is alien abductions and that the government is trying to cover it up.

Two criminals named Max and Frank have arrived in town fresh from Las Vegas. With time kil, they decide to take Tyler's tour to settle an arguement about the existence of Graboids.

A team of scientists find an animal/plant hybrid growing in the valley that proves to be just as deadly as it is strange. Burt, Tyler, and Cletus join forces with them to figure out how to destroy it before it spreads out of the valley.

An Ass-Blaster is sighted in the valley, already having killed two people. After attempting to track it down, Burt and Tyler learn to their frustration that the Ass-Blaster is private property and must be taken in alive...

Burt tracks down and kills a Shrieker out in the valley, only to find out it was part of a government funded project to train Shriekers for rescue missions. But when a storm knocks damages the equipment controlling them, the remaining Shriekers escape and begin to multiply.

Burt barely rescues newcomer (and owner of the local tour business) Tyler Reed from El Blanco, and the trouble isn't over yet. El Blanco is becoming more aggressive by the day and the residents of Perfection have to figure out why before they become the next meal.

Three people are found dead in an abandoned silver mine, their bodies completely drained of all fluids.
