Secreted by the mysterious Mugwumps of Interzone, Mugwump Jism is a colorless liquid that produces intoxicating effects on humans.
In fact, Mugwump Jism actually comes in two finely distinguished varieties, with similar effects. Strangely, what excites the Mugwumps (who are sentient bipeds of about the same size as humans, and appear to be some form of amphibian) to produce this drug is artistic creation, especially of a literary variety.
However, they do produce it even without this inspiration, albeit at a slower rate, and it is a sad but not uncommon sight in Interzone to see a chained Mugwump surrounded by a small circle of addicts sucking upon its excretions.

Bomb the Base “Bug powder dust” speaks about the Mugwump Jism and the Black meat. Great tune.
