from the movie The Princess Bride. A fire swamp is a mythical place in the movie, a R.O.U.S is a rodent of unusual size that resides in said fire swamp, and I'm assuming a fire bog is a potential location in Glitch.
I was just thinking that there should be animals in the bog that were bog-animals. Weird to see a chicken there. R.O.U.S's is interesting. Maybe newts? Frogs? Swamp birds?
