What is "graboid"

The Graboid is a fictional species of sandworm that acts as the primary antagonist of the Tremors franchise. The creature made its debut in the 1990 film Tremors (although the name "Graboid" was only mentioned briefly), and reappeared in its four sequels and the Tremors television series.

The Graboid was named by Walter Chang ( Victor Wong), a store owner who later gets eaten by one in his own store. The only other person in the first film to use the term "Graboid" is Val McKee ( Kevin Bacon). In the second movie Earl Bassett ( Fred Ward) recalls the name "Graboid". The creature is similar to the legendary Mongolian death worm. According to UGO.com, "Graboids are to the desert what sharks are to the ocean".

Graboids have three known stages of life:

• The first is the underground dwelling stage, dubbed the "Graboid," and the most well-known form of the creature.
• The second is the walking stage when the Graboid leaves its underground skin and grows two legs, dubbed the "Shrieker."
• The third is the flight stage where they still have the appearance of stage two but with wings, and a tail that launches flame, dubbed the "AssBlaster".
• Another stage has been shown in the early parts of the fourth film. This stage resembles legged larvae, able to jump out of earth onto the prey.
