I'm normally an avoid-spoilers-and-be-patient sort, but I keep looking at them for this because they keep being stuff I'm extremely into. You happened to hit one of my favorite creatures with this one, so my interest couldn't be higher right now!
Aw, appreciate it. It'll be interesting working with them, because I usually think of rats as being larger characters, but in this case they're more like weird little gremlins. I mean not THAT short, but they will be one of the few enemies Mezz faces that's not taller than he is.
