The Songs of the Frog-Men

In the Mere of Dead Men, all wise travelers carry cotton balls and wax to stop up their ears.  At dusk, as the gas flats erupt and the Stranger begins to lurk at the edge of a campfire, one Frog-Man will climb as high as possible and begin to sing a froggy, croaking song.  All Frog-Men in the area will choose either to take up the song, or to furiously rip the initiator to shreds. It's not clear how they choose, as all the songs sound exactly the same to mammal ears.  Also, repeated exposure to the songs drive one irrevocably insane.  Short term exposure has the following effects, except on the insane, and Frog-Men. No save, but you might have time to stop up your ears once it starts if you move quick.  It's debated, although not widely, if the Frog-Men are naturally immune or have already been driven insane.  It's not widely debated because learned people who rather not spend time thinking about the unseemly, disgusting Frog-Men.
