A sizable, flesh-eating worm called a tikulini, also known as a "mining worm," originated on Jazbina and made its home inside the sun crystal mining passageways. Its blood was green. The term "tikulini" translated to "the demise of countless blades." Its hide possessed sufficient resilience to endure a hit from a lightsaber. While it was thought that they had died out by 0 BBY, there is evidence that at least one of them was still alive at that time.
