To my knowledge, Sligs became industrialized because of a deal they struck with the Glukkons way back when--the ability to walk in exchange for servitude. As for their demeanor, the Crig interviews in Dear Alf suggest that pre-pants Sligs were more than a little bit pissed at having to crawl when every other species walked, but I remember reading somewhere else that Sligs are naturally sweet and caring until it's literally beaten out of them in childhood (probably by Skillya's orders).
Same with the Gluks. Supposedly, Glukkons were an occult-based native species that got along reasonably well with Mudokons until the appearance of the Mudokon Moon, which led the Muds to declare themselves the superior species, which pissed off the Glukkons and drove them to live indoors and nearly destroy themselves and the planet in an industrial revolution.
