i think its goes like this, when hypnocatrice or any other monster that can spit whatever takes a breathe in to inflate some organ that pushes the gasses out they have a falve to their air way that clamps shut so they dont inhail the sleep gas themselves, or gypceros from poisoning itself, barrioth making itself a popsicklefrom the inside out, or the raths from setting their lungs on fire, and since other hypnocatrice havnt gone through the process of expelling te gas themselves their airway is open for the gas to knock them out
