The sprunjer is an extra organ that the Nudist Alien Scammers species have underneath their chin. Its purpose is detecting information, engorging itself in the presence of records, codes, or even hairs that are so much as shaped as the number six. It resembles a bullfrog or toad's throat sounds when it detects high levels of information.
It appears to give an orgasmic feeling to the Nudist Alien Scammers. This happens when the individual detects information, often by sniffing or eating an interesting object.
