Tzur'qipat
this was the Yuuzhan Vong name for the technology that combined a living tzur with an qipat firewasp in a large shell, providing a Yuuzhn Vong warrior with a way of creating a smoke screen. Inside the shell of the tzur'qipat, the tzur was held in a bucket of salt water, without food. Attached to the top of the shell was the qipat firewasp, held in a blister of nutrients. The body chemistry of the qipat had been altered so that it was incompatible with that of the tzur. When the top of the shell was rapped with a Yuuzhan Vong's knuckles, the qipat was awakened. At the command "yuth ugh', the qipat was released from its blister. The starved tzur immediately consumed it, not realizing that the qipat was actually poisonous. The resulting chemical mixture consumed both creatures, as well as the salt water and the inner surface of the shell, creating a thick smoke which billowed out from the shell. The smoke was noxious to breath and incredibly dense, and Yuuzhan Vong who worked with a tzur'qipat had to wear kavaaviks to see and gnullith breathers to get fresh air.
