The first Sandworm models look nearly identical to the Caterkiller, but with a blue, yellow and white color scheme. The latest model differs greatly from its predecessor: this Sandworm is larger, colored completely green and carries a black cannon on both sides of the head.
Later, a more intimidating Sandworm model was created by Dr. Robotnik during his occupation of Flickies' Island. This one tried to attack Tails and Willie Waddle in the Scorchio Zone. Willie, a comedian, told the Sandworm a joke, distracting it and allowing Tails to defeat it.
Powers and abilities
Sandworms have been modified to function in a desert environment. They can quickly burrow through sand, and when they detect enemy on the surface it will burst out to attack. Later models were equipped with powerful laser cannons.
