The Guide entry on toadstool mandarins and their effect on people.
Toadstool mandarins are a form of toxic jellyfish whose tentacles are loaded with entheogenic venom. The effects of a mandarin sting are threefold. The first is a sharp stinging sensation; the second a nasty red welt, which may fester if not treated with a salve of toadstool mandarin doo-doo. And the third is a bolt of self-awareness, thanks to the entheogens in the venom. Having been stung, a victim's typical reaction will be something like:
Owww. Zark, that hurts.
Oh no. Look at this nasty red welt. I'm in the swimsuit competition later.
