A gas extracted from the lymphatic fluid of the Shaking Chewboi, a parasitic animal found in the nerve tissue of the Krezonian Merchant Caste. While the host lives, the parasite is happy, humming, harmless, and all’s right with the multiverse. However, upon the death of its Krezonian host,  the Shaking Chewboi community becomes testy and disgruntled. It collectively shows its displeasure by belching an extremely potent nerve gas that causes muscle cramping, nausea, labored breathing, some light vomiting, and finally slow asphyxiation in its victims. In this case, “victim” is defined as any off-Krezon creature, sentient or non, within a 7,580,973-pace radius of the deceased Krezonite. Krezonians are the second least popular beings (see: Dromo Rustlers, Lyconian) in the known multiverse. One Krezonite sniffle can clear an entire planet within ten martrons. In Cycle 25 AnarchEra, a committee of wealthy and very lonely Krezonian merchants commissioned a team of Vercadian Andromedicones to find a cure for this very social disease. The Andromedicones found that they could coax the Shaking Chewboi from the Krezonian host by dangling a juicy, pulsing bit of Neurolinium tissue (developed by the Andromedicones for the high speed, controlled responses needed in their incredibly dangerous and incredibly expensive Vercadian Protector Androids) in front of the parasite’s sensing apparatus. The only payment asked for the operation was that the Andromedicones be allowed to keep the parasites they extracted. Today the planet Vercadia is virtually covered with warehouses containing bubbling, buzzing vats of humming Chewboi nestled in great nests of Neurolinium (Chewboi farms). By cutting off the current to the nests, every so often, the Vercadian Andromedicones are able to collect and bottle the very deadly Krezonian Nerve gas, their second largest source of income. A sad note: Krezonian Merchants soon found that they remained the second least popular beings in the known multiverse, even without the help of the Shaking Chewboi. Though the cause is unknown, it is suspected that centicycles spent as hosts for the death-dealing parasites has had a deleterious effect on the Krezonian Merchant Caste personality.
