Yep, when I ran that module for my kids, I just used generic kobold stats for the Meepster. In retrospect, I would probably switch out the skill points in Profession(Miner) for Handle Animal. (There must be some reason why he, rather than another kobold, is the dragon wrangler, right? Not that Handle Animal ranks would actually help with that, but Diplomacy doesn't seem to fit, and kobold clans don't typically have dragons. Your general animal handler would probably be pressed into service for that job ...)
