Dunno if this was a bug or not, however, last night I was going to mess around and kite some of the jhunk near the zone in while I was waiting on a group and I saw one of these in the way of a pull I was going for. I cast dire charm and it landed, voila, instant pet. I didn't really get any info as far as damage output or the likes but I will say that while I was kiting one of the spiders that were un-snareable, the pet had a tendency to pull agro if I wasn't working to maintain it. Happy hunting.
