Zicx

A 'Zicx' was a certain type of insect. They were of special interest to science, due to their relative invulnerability to certain types of damage. In nature, the creatures were quite docile. However, if they even became slightly irritated, they'd unlease a lethal torrent of stings and bites.

History
Some time during 1 ABY, a spacer was tasked by Goru Rainstealer to collect Zicx bugs suspended inside the Great Sarlaac Pit on Tatooine. They were an essential component of the Zicx-bug Bomb.
