There are several species of sophont here that we've not seen in Schlock Mercenary before, and a few that we have. From the head of the line to the back of the line, you're looking at a Unioc, a Fobottr, a Nejjat, a sub-bouncer-sized Vhorwed, Uklakk, a pink Wogni, another Unioc, an unimaginatively named tetrisoid, and a Shla'al on his hover-stump. I'm not sure what the thing with the upside-down head is-- I suspect it's somebody's pet, but I could be wrong. Still, who is to say what's 'upside down' anyway? Depending on the length of its tongue, I expect it can lick its eyebrows in a way humans only fantasize about.
