This creature bears resemblance to the Cloaking Burrow-nit but has a purple shell instead, and the markings on the back are just a pair of blue swirls. The body itself is blue and the bug has red eyes. It behaves exactly like a Cloaking Burrow-Nit except it is enveloped in an eternal cloud of poison which only fades after the creature is defeated, meaning you can only use white Pikmin to defeat it. Apparently, the poison is actually the creature rapidly exhaling. Poisonous Burrow-Nits have pores in their backs that take in the planet's oxygen. They exhale it quickly as a poisonous gas.
