To keep the zombie clown Transadours from brutally attacking clowns for their precious BONK, Minkles created the means for synthesizing and storing BONK. By converting the liquid into aerosol form, it can be inhaled as dust through a ventilator apparatus.
Due to the efficacy of this closed ventilation system, the Evaporators allow the Disgustoids to use smaller amounts of BONK for longer periods. The Evaporators also allow the Disgustoids to be mobile by storing and rucking the evaporator tanks on their backs.
The Evaporators are also used for Minkles’ BONK-fueled Carnival War Machines, such as the Grinders.
