Tremors

1990

March 1, 1990

• Perfection, Nevada
• Unidentified underground creatures consume livestock and the human residents in the town and surrounding valley.
• The blind, worm-like animals travel effortlessly through the Pleistocene alluvial soil, tracking prey by means of sonic vibration.

March 2, 1990

• Townspeople terminate the creatures with crude homemade weapons.
• Existing specimens badly damaged and decomposed. Rhonda LeBeck oversaw removal of the two least-damaged Graboids. They were taken to the college where she was studying, and preserved as well as possible. One currently resides in the Smithsonian. The other is sold to a casino in Laughlin, Nevada.

March, 1990

• A few days later, Survivor Burt Gummmer regrets his decision to give away "his" Graboid. At considerable expense and effort, he reclaimed the head of the most-damaged Graboid, Stumpy. Its head was relatively undamaged, and Burt has a taxidermist mount it, also at considerable expense.
• No living animals found for study.
• Creatures become widely known as Graboids.

Tremors 2: Aftershocks

May 11, 1995

• Petromaya Oil Field Chiapas, Mexico
• Graboids appear in the oil field. Company employees are consumed and oil production is interrupted.
• Desperate oil company executives hire survivors from the 1985 Graboid attack to track down and kill the Mexican Graboids.
• On site Geologist Kate Riley reports Graboids are extremely ancient earth life form.
• Before all Graboids can be eliminated they undergo a highly unusual metamorphosis sub-divding into smaller bipedal surface creatures.Technically blind like the Graboids, these creatures nevertheless efficiently track their prey by sensing heat. Some humans survived by devising methods to disguise their body heat, including using cold blasts from a CO2 fire extinguisher.
• These new creatures become known as Shriekers due to the piercing cry they make when sensing prey.
• Shriekers are reported to be hermaphrodites, reproducing by regurgitating an offspring immediately after the consumption of a meal. This has not been confirmed.
• Note: If Shrieker reproductive rates are shown to be directly proportional to available food supply, a Shrieker "population explosion" is a potential threat.
• According to survivor Burt Gummer, all Chiapas Mexico Shriekers were eliminated by use of an "appropriate" amount of high explosives.
• All remains badly damaged and decomposed. No living animals found for study. Government of Mexico showed no interest in the historical or natural significance of the dead animals, and they were left to be decomposed and eaten (by buzzards).

• Before they can capture a Graboid alive the creatures turn into Shriekers and then again into flying creatures that propel themselves into the air using a chemical reaction generated in their abdomen (tail), these creatures are termed Ass Blasters by Jodi Chang.
