A cherub has recently begun to attract a lot of PC attention (it saw things it shouldn't have, etc). In all the attention they were paying it, an interesting question came up. As cherubs are comprised of a good bit of organic components, do they eat and, if so, what? Likewise, what forms of waist dose it produce and how dose it get rid of those waists -that is to say, do cherub's poop and, if so, in what way? The group is a touch concerned about this as said cherub is currently locked in their Lander...
My knee-jerk reaction is, yes, they must eat (usually some kind of nutraslury or some such, but they don't require much) and their excrement is rather reminiscent of pigeon crap... if just seems somehow appropriate.
