Since this post is so interesting, I think I'll help a little..
Yes, that is Skillya the Slig Queen. Like a slig, she wears pants.. but her face? On something about Dear Alf, Crig made a statement that sligs are UGLY without their masks.. Skillya probably couldn't fit one on.. And that is why. The only difference seems to be that regular sligs have tentacles around their mouths.. as for egglaying, she probably has to get out of her pants to do such a thing.
